TECHNICAL NOTEALUMINUM ELECTROLYTIC CAPACITORS®WITH CONDUCTIVE POLYMER SOLID ELECTROLYTECautions for Using Aluminum Electrolytic Capacitors With Conductive Polymer Solid ElectrolytePlease be sure to read this specification before using this product.Before placing an order, please inquire about the Product Specification to check details.Cautions for Usage1. Solid conductive polymer aluminum electrolyticcapacitors are polarized.• Using a capacitor with reversed polarity causesabnormal current flow, resulting in a short circuit.• Cannot use for the circuit to which the polarityreverses by ripple voltage.2. Prohibited Circuits• Since leakage current problem may arise, capacitorscannot be used in the following circuits.Coupling circuitsCircuits greatly affected by leakage current3. Use capacitors within the rated voltage.• The application of voltages exceeding the ratedvoltage can significantly increase leakage current,resulting in a short failure. Please do not apply avoltage exceeding the rated voltage.4. Be careful of excessive rush current.• Using capacitors in the circuit where excessiverush current passes may cause characteristicdeterioration or a short. When the rush currentexceeds 10 A, we recommend use of protectioncircuits to ensure high reliability.5. Use the allowable ripple voltage and the ratedripple current below the specified values.• When superimposing a ripple voltage on a DC biasvoltage, exercise care that the peak voltage valuedoes not exceed the rated voltage and does notreverse the polarity.• The rated ripple current shall be below the specifiedvalue.6. Changes in characteristics due to operatingtemperature• The characteristics of solid conductive polymeraluminum electrolytic capacitors vary by temperatureas follows. These variations are temporaryand recover when the temperature goes back(except for the case of characteristic deteriorationbecause of high temperatures over a long time).Note that using capacitors over the upper categorytemperature increases leakage current, resulting ina short and destruction.Be careful of the capacitor temperature consideringnot only the ambient temperature where theequipment is placed and the temperature inside theequipment but also radiation heat from the heatingelement inside the equipment, and self-heatgeneration by ripple current.Capacitance expressed in the value at 20°C, 120Hz increases with increased temperature anddecreases with decreasing temperature.Tangent of loss angle (tan) expressed in thevalue at 20°C, 120 Hz is temperature-independent.Equivalent series resistance (ESR) expressed inthe value at 20°C, 100 kHz is temperatureindependent.Leakage current increases with increasedtemperature and decreases with decreasingtemperature.7. Changes in characteristics due to frequency• The characteristics of solid conductive polymeraluminum electrolytic capacitors vary by operatingfrequency as follows.Capacitance expressed in the value at 20°C, 120Hz decreases with increased frequency.Tangent of loss angle (tan) expressed in thevalue at 20°C, 120 Hz increases with increasedfrequency.Equivalent series resistance (ESR) expressed inthe value at 20°C, 100 kHz increases withdecreasing frequency.8. Failure modes of solid conductive polymeraluminum electrolytic capacitors• The failure modes of solid conductive polymeraluminum electrolytic capacitors are a wear-outfailure by deterioration of electrical performance anda random failure by a short. The failure rate level is0.5%/1,000h at the reliability level of 60% with thespecified voltage applied at 105°C.• If a short occurs and continues with the applicationof a voltage exceeding the rated voltage, increasingthe internal temperature, the internal pressureincreases by vaporization of the cathode material,which may cause the aluminum case to come off.9. Operating environments• Do not use capacitors in an environment directlyexposed to water, saltwater spray, oil spill orcondensation.• Do not use capacitors in an environment filled withtoxic gas such as hydrogen sulfide, sulfurous acid,nitrous acid, chlorine, ammonia, etc.• Do not use capacitors in a place exposed to ozone,ultraviolet rays, or radiation.10 . Fumigation ProcessCAT.No.2010/2011E

®ALUMINUM ELECTROLYTIC CAPACITORSTECHNICAL NOTEWITH CONDUCTIVE POLYMER SOLID ELECTROLYTE• Before transportation of electronic equipment tooverseas, fumigation process may be subjected towooden packing material with a halogen(compound) gas such as methyl bromide. Exercisecare that this halogen gas may corrode capacitors.Also, be careful of epidemic preventive agent ascorrosive component such as halogen may becontained.11. The case of solid conductive polymer aluminumelectrolytic capacitors and the cathode terminal arenot insulated.• The case and the cathode terminal are not insulatedas being connected through inconstant resistance.12. Double-sided PCB’s•When using capacitors on a double-sided PCB,exercise care that the wiring pattern does not touchthe area where the capacitors are mounted. Failureto do so may cause a short to occur to the PCBdepending on the mounting conditions.13. Regarding Connection of Solid ConductivePolymer Aluminum Electrolytic Capacitors• When connecting more than one capacitor inparallel, consider the current balance.14. Other Notes• Do not use capacitors on a circuit where rapidcharge and discharge are repeated.• Electrical characteristics of capacitors vary byvariations in temperature and frequency. Pleaseconsider these variations when designing a circuit.Cautions for Mounting1. Cautions for Mounting• Do not reuse capacitors that have been assembledin a set and energized. Capacitors cannot be reusedexcept for those which have been measured onelectrical performance during periodic inspection.• Before mounting, confirm the capacitor ratings(rated capacitance and rated voltage).• Capacitors may generate transient recovery voltage.In this case, discharge through a resistor of about1 k.• Before mounting, confirm the polarity of capacitor.• Do not drop capacitors onto a floor nor use them.• Do not mount deformed capacitors.• Do not mount heating parts around capacitors andon the back of the PCB under or back of capacitors).2. Do not apply excessive pressure to the capacitoror its terminals• Be careful of the shock force that can be producedby absorbers, product checkers, and centering onautomatic inserters and installers.3. Soldering• Do not solder capacitor body by dipping into meltedsolder.• Soldering conditions (preheating, solderingtemperature, terminal dipping time) should be withinthe ranges specified in the catalog or the deliveryspecification.• Flux should not adhere to the parts other than theterminals.• When using a soldering iron, avoid excessive stressto capacitor body.• In reflow soldering, the reflow should be conductedonce. Please be sure to consult with us if reflowmust be conducted twice.• Although leakage current may increase (from a fewµA to hundreds of µA) after soldering, it can bereduced through self-repair by applying voltage. It isadvised to operate the set properly after treatingwith the recommended voltage.• In case of a long-term use of equipment, control thesoldering characteristics so that capacitors and PCBdo not fail to connect to avoid abnormal currentpassage by a failure of soldering to mount.4. Handling after Soldering• Do not tilt, fall, raise or twist capacitor body.• Do not pick up or move PCB by holding a capacitor.• Do not bump capacitors against objects. Whenstacking PCB’s, make sure that capacitors do nottouch the PCB’s or other components.• Do not subject capacitors to excessive stress.5. Cleaning after Soldering• Recommended cleaning methodCleaning solutions:(a) CLEANTHROUGH 710M, 750H, 750L(b) PINEALPHA ST-100S(c) Techno Care FRW-4~17(d) Isopropyl alcohol (2-propanol)Cleaning conditions:(a) The temperature of cleaning solution shall beless than 60°C.(b) Use immersion or ultrasonic waves within twominutes.(c) After cleaning, capacitors and PCB’s shallthoroughly be rinsed and dried with hot blastfor more than 10 minutes. The temperature ofsuch breeze should be less than the uppercategory temperature.(d) After cleaning, do not keep capacitors incleaning solution atmosphere or airtightcontainers.CAT.No.2010/2011E

TECHNICAL NOTEALUMINUM ELECTROLYTIC CAPACITORSWITH CONDUCTIVE POLYMER SOLID ELECTROLYTE®• During cleaning, control the cleaning solutionagainst contamination.6. Fixing adhesives and coating materials.• Do not use halogenated fixatives and coatings.• Before using a fixative or coating, remove fluxresidues and contaminants from between the PCBand the sealing section of capacitors.• Dry the cleaning solution before using the adhesiveor coating.• Do not cover up all the sealing sections (terminalside) of capacitors with the adhesive or coating.• Heat curing conditions of fixative and coating.Other Cautions1. Do not directly touch the terminals of solid conductivepolymer aluminum electrolytic capacitors.Failure to do so can cause electric shock or burns.Before use, allow capacitors to discharge through a1k resistor (with a sufficient margin to the heatgeneration capacity) as needed.2. Do not short-circuit between the terminals ofthe solid conductive polymer aluminum electrolyticcapacitors with electric conductor. Do not subjectcapacitors to conductive solutions such as acidand alkaline water solutions.3. Periodic inspection should be performed on thecapacitors for the industrial equipment application.Check the following checkpoints.• Visual inspection to check for significant defects.• Electrical performance: leakage current, ratedcapacitance, tangent of loss angle, ESR, and itemsspecified in the catalog or delivery specification.4. Be careful of the following cases of emergency.• In case of a short during use of capacitors in sets,producing gas, turn off the main power of the set orunplug the power cord from the outlet.• In case of a short, producing gas, it may take a fewseconds to a few minutes depending on theconditions. Therefore, ensure that the protective circuitof the power supply works during this time.• If the gas gets in your eyes, rinse them immediately.Gargle if the gas is inhaled.• Do not lick the electrolyte of capacitors. When theelectrolyte gets on your skin, wash it off with soapimmediately.• During delivery, capacitors are stored in airtightmoistureproof bags to ensure satisfactory soldering.Once the bag is opened right before mounting, it isbetter to use up the capacitors. If some are unavoidablyleft over, return them to the moistureproof bag,and seal the opening hermetically.• Solid conductive polymer aluminum electrolyticcapacitors may have increased leakage currentwhen unused or stored for a long time after mountedon equipment. This phenomenon often occurs athigh ambient temperatures; however, leakagecurrent will decrease through voltage treatment. Ifleakage current still increases after a lapse of morethan one year at ambient temperature (shorter timeat high temperatures), treat with voltage as needed.In design of equipment, consider the effect ofincrease in initial current, and install protectivecircuits as needed.Please check that recommended voltage treatmentconditions are provided for each series.• Do not store capacitors in an environment directlyexposed to water, saltwater spray, oil spill orcondensation.• Do not store capacitors in an environment filled withtoxic gas such as hydrogen sulfide, sulfurous acid,nitrous acid, chlorine, ammonia, etc.• Do not store capacitors in a place exposed to ozone,ultraviolet rays, or radiation.6. Please take the following actions whendisposing of solid conductive polymer aluminumelectrolytic capacitors.• Entrust to specialists of industrial waste treatment forincineration.7. Others• Before using capacitors, check the details of thisdelivery specification and catalog as well as thefollowing.Technical Report of Japan Electronics and InformationTechnology Industries AssociationEIAJ RCR-2367CGuideline of notabilia for fixed aluminum electrolyticcapacitors for use in electronic equipment5.

ALUMINUM ELECTROLYTIC CAPACITORS®Cautions for Using Aluminum Electrolytic CapacitorsPlease read product specifications before using ELNA products.The following cautions should be observed when using our aluminum electrolytic capacitors to assure their maximumstability and performance. When your application design conditions or operating conditions exceed the limit of theproduct specification, please contact us. If used under conditions beyond the limit of our specifications, it may causedefects such as short circuit, open circuit, leakage, explosion or combustion.Cautions for usage1. DC electrolytic capacitors are polarized.• If used with a wrong polarity, it creates an abnormalcurrent resulting in a short circuit or damage toitself. Use DC bipolar electrolytic capacitors for usewith uncertain or unknown polarity. DC capacitorscannot be used in AC circuits.2. Use within the rated voltage.• If a voltage exceeding the rated voltage is applied,it may cause characteristic deterioration or damagedue to the increased leakage current.• When ripple current is loaded, make sure that thepeak value of the ripple voltage does not exceedthe rated voltage.3. Using for power supply circuit.• While aluminum electrolytic capacitors are operatedelectrolyte liquid inside dries up and E.S.R.(Equivalent Series Resistance) of the capacitorincreases. In case operated longer than rated lifetime, the capacitance much decreases, tangent ofloss angle and E.S.R. much increases. Thereforefor some case the sum of bias direct voltage andthe peak of ripple voltage is over the rated voltageof the capacitor.• For any type of circuit, in case the sum of biasdirect voltage and the peak of ripple voltage is overthe rated voltage of the capacitors or in case theminimum voltage is lower than 0 (zero) volt, thevoltage control for the capacitors shall be provided.4. Do not use in a circuit which requires rapidcharging or discharging.• If used in a circuit requiring rapid charging or discharging,it may cause characteristic deteriorationor damage to itself due to the heat generated insidethe capacitor. In such cases, contact us for ourrapid charging/discharging capacitors.5. Use within the rated ripple current.• If applied ripple current exceeds rated ripple current,the life of the capacitor may be shortened, or in anextreme case it gets destroyed due to its internal heat.Use high-ripple type capacitors for such circuits.6. Changes in characteristics due to operatingtemperature.• The characteristics of an electrolytic capacitor willchange with a change in the temperature. Suchchanges are temporary and the original characteristicswill be restored at the original temperature (ifCAT.No.2010/2011Ethe characteristics are not deteriorated by remainingat a high temperature for a long time). If used at atemperature exceeding the guaranteed temperaturerange, the capacitor may be damaged due to theincreased leakage current. Pay attention to thecapacitor temperature being affected by the ambienttemperature of the unit, the temperature inside theappliance, the heat radiated by another hot componentin the unit and the heat inside the capacitor itself dueto the ripple current.(1)The electrostatic capacitance is normally shownas the value at 20°C-120Hz. It increases as thetemperature raises and decreases as it lowers.(2)The tangent of loss angle (tan) is normallyshown as the value at 20°C-120Hz. It decreasesas the ambient temperature gets high andincreases as it gets low.(3)The leakage current increases as the temperaturegets high and decreases as it gets low.7. Changes in the characteristics due to frequency.• The characteristics of an electrolytic capacitor willchange according to the change in the operatingfrequency.(1)The electrostatic capacity is normally shown asthe value at 20°C-120Hz. It decreases as thefrequency increases.(2)The tangent of loss angle (tan) is normallyshown as the value at 20°C-120Hz. It increasesas the frequency gets high.(3)The impedance is normally shown as the value at100kHz 20°C. It increases as the frequency lowers.8. Aluminum electrolytic capacitor life.• The life of an aluminum electrolytic capacitor terminateswhen it fails due to the deterioration in itselectronic characteristics. Temperature and theripple current since they especially affect the life.See chart on page.9. Changes in aluminum electrolytic capacitorsduring storage.• After storage for a long period, whether unused ofmounted on the appliance, the leakage current ofan aluminum electrolytic capacitor will increase.This tendency is more prominent when the ambienttemperature is high. If a capacitor has been storedfor more than 2 years under normal temperature(shorter if high temperature) and it shows increasedleakage current, a treatment by voltage applicationis recommended. Addition of a protective circuit in

®ALUMINUM ELECTROLYTIC CAPACITORSthe design of the appliance is also recommended,considering the effect of the initial increased current.10. Insulation between the capacitor case and thecathode terminal.• The capacitor case and the cathode terminal areconnected through the electrolyte which hasuncertain resistance. If a complete insulation of thecase is necessary, add an insulator at assembly.11. External sleeve.• During a preheating or a hardening of mountingadhesive may cause a sleeve cracked.The capacitors are usually sleeved with poly vinylchloride or poly ethylene terephthalate for theindication purpose only. Please do not consider itas an insulation.12. Fumigation Process• When exporting electronic equipment abroad,fumigation process may be performed on woodenpackaging material with a halogen (compound) gassuch as methyl bromide. Exercise care as thishalogen gas may corrode capacitors. Also, usecaution to epidemic preventive agent as corrosivecomponent such as halogen may be contained.13. Specific Operating Environments• Capacitors may corrode when stored or used in aplace filled with acidic toxic gases (such ashydrogen sulfide, sulfurous acid, nitrous acid,chlorine, bromine, methyl bromide, etc.)If capacitors are used or stored in suchenvironments, please let us know.14. Use at a high altitude• The use of capacitors at high altitudes such as onan airplane causes a large difference between theinternal pressure of the capacitors and the atmosphericpressure. However, there is no problem inuse under atmospheric pressure up to about analtitude of 10,000 meters. Please check theoperation of electronic equipment at the operatingenvironmental temperature because thetemperature lowers with increased altitude.15. Hole pitch adjustment of the PCB to thecapacitors.• Set the hole pitch of the PCB to the lead pitch (the“F” distance in the catalog) of the capacitor. Becareful since a short circuit, a cut or an increasein the leakage current etc. may be caused by thestress given to the lead wire terminals due to thedifference between the hole pitch and the leadpitch.16. Capacitors with pressure valves.• A part of the capacitor case is made thin to havethe function as the pressure valve in order to preventexplosion due to the rise of inside pressurewhen a reverse or excessive voltage is applied tothe capacitor. Once it has worked as a valve, thewhole capacitor needs to be replaced since thevalve will not restore.• When you use a capacitor with pressure valve,provide certain space above the pressure valve asbelow to prevent an interference when it works asa valve.Diameter of the capacitor(mm)Required spaceabove the valve (mm)18 to less17. Double-sided PCB’s• When you use electrolytic capacitors on a doublesided PCB, be careful not to have the circuit patternrun under where the capacitor is mounted.Otherwise it may cause a short circuit on the PCBdepending on the condition of mounting.18. Regarding to connection of capacitors• Aluminum electrolytic capacitor has electrolyte liquidso that the most portion of electric losscharacteristics came from E.S.R(Equivalent SeriesResistance) of electrolyte liquid. Therefore thecapacitor is an electronic devise which can flow highripple current in case the temperature increases andit decreases E.S.R.In case connecting two capacitors or more, E.S.R. ofthe capacitors is close to the resistance of the circuit.Therefore in case current is unbalanced and somecapacitors has high ripple current, temperatureincrease, it makes more high current and finally it isover the rated ripple current.For parallel connection of capacitors the properdesign of electric circuit such as balancing of eachcapacitors resistance or control of total ripple currentshall be provided to avoid excess ripple current andvoltage.• When two or more capacitors are arranged inseries, the voltage given to each capacitors shallbe kept below the rated voltage level, by also givingconsideration to the balance of the voltageimpressed on the capacitors. Further, partialpressure resistor which considers leakage currentshall be provided parallel to each condenser not tohave over-voltage impressed on.Balance resistance are explained on p.106 of ourCatalog.Cautions for Mounting1. Cautions for mounting.• Check the ratings (electrostatic capacitance andrated voltage) of the capacitor before mounting.• Check the polarity of the capacitor to the chassis.• Do not drop the capacitor to the floor. Do not use2.020 to 403.0CAT.No.2010/2011E

ALUMINUM ELECTROLYTIC CAPACITORS®the dropped capacitor.• Do not deform the capacitor for mounting.2. Do not apply excessive pressure to the capacitor,its terminals or lead wires.• Make sure that the contact path of the capacitormeets the hole pitch of the PCB before mounting.• Transient recovery voltage may be generated in thecapacitor due to dielectric absorption. If required,this voltage can be discharged with a resistor witha value of about 1 k.• A PCB self-standing (snap-in) type capacitor shouldbe pushed to the end (till there is no space) to thePCB for mounting.• Do not set the automatic insertion machine to clinchthe capacitor lead wires too strong.• Pay attention to the impact given by the componentreceptacles of the automatic insertion/mountingmachines and the product checker, and fromthe centering operation.3. Soldering.• Do not dip the capacitor into melted solder.• The soldering conditionsChip type : Please refer to 11 page.small and large type : 260°C, 10 s (max.)The preliminary heating and other conditionsdescribed in the catalog or product specifications.• Do not flux other part than the terminals.• If there is a direct contact between the sleeve ofthe capacitor and the printed circuit pattern or ametal part of another component such as a leadwire, it may cause shrinkage of crack.• When you use the capacitor with its sleeve touchingdirectly to the PCB, excessive solder temperatureor excessive soldering time may cause thesleeve to shrink or crack during the heat.• If the application is for extended use, understandand manage the soldering characteristics to avoidabnormal current caused by a contact failurebetween the capacitor and the PCB.4. Handling after soldering.• After soldering, do not tilt, push down or twist thecapacitor.• After soldering, do not hold the capacitor as ahandle to carry the PCB.• After soldering, do not hit the capacitor with anyobstacle. If PCB’s are piled up for storage, thecapacitor should not touch another PCB or component.5. Cleaning after Soldering• Recommended cleaning method(1)cleaning solutions:(a) CLEANTHROUGH 710M, 750H, 750L(b) PINEALPHA ST-100S(c) Techno Care FRW-4~17(d) Isopropyl alcohol (2-propanol)CAT.No.2010/2011E(2)Cleaning conditions:(a) The temperature of cleaning solution shall beless than 60°C.(b) Use immersion or ultrasonic waves within twominutes.(c) After cleaning, capacitors and PCB’s shallthoroughly be rinsed and dried with hot blastfor more than 10 minutes. The temperature ofsuch breeze should be less than the uppercategory temperature.(d) After cleaning, do not keep capacitors incleaning solution atmosphere or airtightcontainers.• During cleaning, control the cleaning solutionagainst contamination.6. Fixing adhesives and coating materials.• Do not use fixing adhesive or coating materialcontaining halogen-based solvent.• Before applying the fixing adhesive or the coatingmaterial, make sure that there is no remaining fluxor stains between the PCB and the sealed part ofthe capacitor.• Before applying the fixing adhesive or the coatingmaterial, make sure that the detergent etc. hasdried up.• Do not cover the whole surface of the sealed part(terminal side) of the capacitor with the fixing adhesiveor the coating material.• Observe the description in the catalog or the productspecifications concerning the thermal stiffeningconditions of the fixing adhesive or the coatingmaterial. (If there is no such description, contactus.) When both discrete and SMT components areon the same PCB, the fixing material for the SMTcomponents may cause crack, tear or shrinkage onthe external sleeve depending on the thermalstiffening condition.• Recommended fixing adhesives and coatingmaterialsFixing adhesives : Cemedine 210, 501, 540, 545N, DiabondDN83K, DA3288, Bond G103Coating materials : Taffy TF1159, HumiSeal 1B66, 1A27NSOther Cautions1. Do not touch capacitor terminals with bare hands.You may get electric shock or your hand may beburnt. Discharge it with a 1 K resistance before useif necessary.2. Do not short the capacitor terminals with a conductor.Do not spill conductive solution including acid or alkalinesolution on the capacitor.3. Periodical inspections should be establishedfor the capacitors used in industrial appliances.• The following items should be checked:

®ALUMINUM ELECTROLYTIC CAPACITORS(1)Appearance : Check if there is any open valve orleakage.(2)Electronic performance : Check the leakagecurrent, the electrostatic capacitance, the tangentof loss angle and other items described in thecatalog or the product specifications.4. Take the following measures in case of emergency.• If you see gas coming out of the capacitor valvewhen the set is in operation, turn off the powerswitch of the unit or unplug the power cord fromthe outlet.• Keep your face away from the capacitor pressurevalve, since the high temperature gas at over100°C bursts out when the valve works. If the gasgets into your eyes or your mouth, wash your eyesor your mouth. Do not ingest the capacitor electrolyte.If the electrolyte gets on your skin, wash it outwith soap.5. Storing conditions.• Avoid high temperature or high humidity whenstoring capacitors. Keep the storing temperature at5 to 35 and the relative humidity not more than75%.• The leakage current of an aluminum electrolyticcapacitor tends to increase when stored for a longtime. This tendency becomes more prominent if theambient temperature is high. The leakage currentwill be decreased by voltage application. Ifnecessary, treatment by voltage application shouldbe made on the capacitors which have been storedfor a long period (more than 2 years afterproduction).• Do not store capacitors at a place where there isa possibility that they may get water, salt or oil spill.• Do not store capacitors at a place where the aircontains dense hazardous gas (hydrogen sulfide,sulfurous acid, nitrous acid, chlorine, ammonia,etc.).• Fumigation treatment with toxic gas covering thewhole wooden container frames as moth proofingduring shipment may leave residual toxic gas.• Do not store capacitors at a place where it getsultraviolet or radioactive rays.6. Disposing of capacitors.• Punch a hole or crush the capacitors (to preventexplosion) before incineration at approved facility.• If they are not to be incinerated, bring them to aprofessional industrial waste disposal company.7.

TECHNICAL NOTE1 General Description of Aluminum ElectrolyticCapacitors1-1 The Principle of CapacitorThe principle of capacitor can be presented by theprinciple drawing as in Fig.1-1.When a voltage is applied between the metal electrodesplaced opposite on both surfaces of a dielectric,electric charge can be stored proportional to thevoltage.QCVQ : Quantity of electricity (C)V : Voltage (V)C : Capacitance (F)StALUMINUM ELECTROLYTICCAPACITORSAnode foilAnodic oxide filmElectrolyte(True cathode)1-2 Equivalent Circuit of the CapacitorThe electrical equivalent circuit of the aluminum electrolyticcapacitor is as presented in Fig. 2.D1Fig.1-2Separator sheetimpregnated with electrolyteCathode foil(Virtually, electrode forcathode extraction)Natural air oxide film®R1C1R2C2LR3Fig.1-1C. called the capacitance of capacitor, is expressed bythe following expression with the electrode area S[m 2 ],the electrode spacing t [m] and the dielectric constantof dielectric “”:SC[F]0—— t0 : Dielectric constant in vacuum (8.8510 12 F/m)Table 1Dielectric Dielectric Constant Dielectric Dielectric ConstantAluminum oxide filmMylarMica7 to 83.26 to 8Porcelain (ceramic)PolystyreneTantalum oxide film10 to 1202.510 to 20L L0 2The dielectric constant of an aluminum oxide film is7 to 8. Larger capacitances can be obtained by enlargingthe electrode area S or reducing t.Table 1-1 shows the dielectric constants of typical dielectricsused in the capacitor. In many cases, capacitornames are determined by the dielectric material used,for example, aluminum electrolytic capacitor, tantalumcapacitor, etc.Although the aluminum electrolytic capacitor is small,it has a large capacitance. It is because the electrodearea is roughened by electrochemical etching, enlargingthe electrode area and also because the dielectricis very thin.The schematic cross section of the aluminum electrolyticcapacitor is as in Fig.1-2.R1 : Resistance of terminal and electrodeR2 : Resistances of anodic oxide film and electrolyteR3 : Insulation resistance because of defective anodicoxide filmD1 : Oxide semiconductor of anode foilC1 : Capacity of anode foilC2 : Capacity of cathode foilL : Inductance caused by terminals, electrodes, etc.2 About the Life of an Aluminum ElectrolyticCapacitor2-1 Estimation of life with minimal ripple current(negligible).Generally, the life of an aluminum electrolytic capacitoris closely related with its ambient temperature and thelife will be approximately the same as the one obtainedby Arrhenius’ equation.T0T——10 )………………(1)Where L : Life at temperature T)L0 : Life at temperature T0The effects to the life by derating of the applied voltageetc. are neglected because they are small comparedto that by the temperature.CAT.No.2010/2011E

®ALUMINUM ELECTROLYTICCAPACITORS2-2 Estimation of life considering the ripple current.The ripple current affects the life of a capacitorbecause the internal loss (ESR) generates heat. Thegenerated heat will be :P I 2 R………………(2)Where l : Ripple current (Arms)R : ESR ()With increase in the temperature of the capacitor:I 2 •Δ T R………………(3)A • HWhere Δ T : Temperature increase in the capacitorcore(deg.)I : Ripple current (Arms)R : ESR ()A :Surface area of the capacitor (cm 2 )H : Radiation coefficient (Approx. 1.5 2.0 10 -3 W/cm 2 )The above equation (3) shows that the temperature ofa capacitor increases in proportion to the square ofthe applied ripple current and ESR, and in inverseproportion to the surface area. Therefore, the amountof the ripple current determines the heat generation,which affects the life. The value of Δ T varies dependingon the capacitor types and operating conditions.The usage is generally desirable if Δ T remainsless than 5. The measuring point for temperatureincrease due to ripple current is shown below ;Measuring pointTECHNICAL NOTET0TΔT0ΔTL Lr 2 10 K 10 ………(5)Where Lr : Life at the upper category temperaturewith the rated ripple current (h)ΔT0 : Temperature increase at capacitor core,at the upper category temperature (deg.)(3) The life equation considering the ambient temperatureand the ripple current will be a conversion ofthe above equation (5), as below :T0TI ΔT0 1 L Lr 2 10 K I 0 10 ……(6)Where l 0 : Rated ripple current at the upper categorytemperature (Arms)I : Applied ripple current (Arms)Since it is actually difficult to measure the temperatureincrease at the capacitor core, the following table isprovided for conversion from the surface temperatureincrease to the core temperature increase.2 The life expectancy formula shall in principle beapplied to the temperature range between the ambienttemperature of 40 and upper categorytemperature.

Voltage caused in such case is called recoveryvoltage. Following is the process that causes thisphenomenon :• When the voltage is impressed on a dielectric,electrical transformation will be caused inside thedielectric due to dielectric action, and electrificationwill occur in positive-negative opposite to the voltageimpressed on the surface of the dielectric. Thisphenomenon is called polarization action.• After the voltage is impressed with this polarizationaction, and if the terminals are discharged till theterminal voltage reaches 0 and are left open for a while,an electric potential will arise between the two terminalsand thus causes recovery voltage.• Recovery voltage comes to a peak around 10 to 20days after the two terminals are left open, and thengradually declines. Recovery voltage has a tendency tobecome bigger as the component (stand-alone basetype) becomes bigger.• If the two terminals are short-circuited after therecovery voltage is generated, a spark may scare theworkers working in the assembly line, and may put lowvoltagedriven components (CPU, memory, etc.) indanger of being destroyed. Measures to prevent this isto discharge the accumulated electric charge withresistor of about 100 to 1k before using, or ship outby making the terminals in short-circuit condition bycovering them with an aluminum foil at the productionstage. Please consult us for adequate procedures.3-3 Calculation Example.Calculate the value of the balance resistance in thecase of connecting two 400V 470µF ( LC standardvalue : 1.88mA) capacitors in series.R1 400(V)1.88(mA)213(k)CAT.No.2010/2011E

Fig. 3-1shows its effects with values of the polarizationresistance inversely proportional to the corrosion rateusing the AC impedance method(FRA). This indicatesthat the cathode foil used in the High reliability capacitorshas the polarization resistance higher than that of theconventional capacitors owing to corrosion inhibition.Resistance (W)High reliability capacitorsFig. 3-1Reference5-2 Sealing material permeability of electrolyteTo ensure long life, a low permeable lactone solvent forthe sealing material is used as the main solvent of theelectrolyte of the High reliability capacitor.

ELECTRIC DOUBLE LAYER CAPACITORSCautions for Using Electric Double Layer Capacitor (DYNACAP , POWERCAP)Usage1. Electric double layer capacitors (EDLC) use aconductive organic electrolyte.The use at excessive mounting temperature orexceeding the upper category temperature cancause the electrolyte to leak. Especially,coin andmultilaver coin types for the memory backup (DB,DBN, DBJ, DBS, DX, DXJ, DXN, DXS, DH, DK, DC,DCK, DS, and DSK series) excluding the DZ, DZH,DZN and DP series use a low elastic plastic as thesealant in the cell construction like coin batteries;therefore, avoid using such capacitors in the vicnityof automotive equipment with steep temperaturechange, and heating element such as motor, relay,transformer, power IC, etc. because of the risk ofleakage of electrolyte.2. Since EDLC is polarized, do not apply areversed voltage.EDLC is polarized. If a reversed voltage is appliedfor a long time, the leakage current will increaseabruptly, which may cause a decrease in thecapacity, an increase in the internal resistance, andcausing leakage or damage to the product in somecases.3. Do not apply any voltage higher than theoperating maximum voltage (this means the surgevoltage in the case of short-time charge).If an overvoltage is applied to the product, theleakage current will increase abruptly and theproduct will become overheated, which may causea decrease in the capacity, an increase in theinternal resistance, and causing leakage or damageto the product in some cases.4. Do not use smoothing a power supply ( forabsorbing its ripple).Since the internal resistance of EDLC is high, theproduct will be overheated if it is used for smoothinga power supply (for absorbing its ripple), which maycause a decrease in the capacity. an increase in theinternal resistance, and causing leakage ordamage to the product in some cases .5. Do not use in a circuit where quick charge anddischarge are repeated Very often.In a circuit where quick charge and dischargeare repeated very often , the product will becomeoverheated, which may cause a decrease in thecapacity, an increase in the internal resistance, andcausing leakage or damage to the product in somecases.Reduce the charge and discharge currents whileselecting a product with low internal resistance, andrnake sure that the product surface temperaturedoes not rise.6. EDLC life depends heavily on the ambienttemperature.The lifetime of EDLC is seriously affected bychange in ambient temperature. If the temperatureis lowered by 10, the lifetime will be approximatelydoubled. Therefore, the product should beused at a temperature lower than the guaranteedmaximum value for maximum life.If the capacitor is used at a temperatureexceeding its maximum guaranteed temperature,not only is its life shortened, but increased vaporpressure of electrolyte or electrochemical reactionsmay increase the internal pressure, and causingleakage or damage to the product in some cases.7. Note that a voltage drop in EDLC occurs duringbackup.In a case where discharge current is large, or alarge current flows instantaneously. an electricdouble layer capacitor may not operate at the startof discharge because of a large voltage drop (IRdrop) caused by the product with the DC internalresistance.Please consult us for a large dischargecurrent (inthe case of other series except DZ, DZH, DZN andDP series: when larger than 1mA1×CFasthe internal resistance varies by each series (Recommendationdischarge current: less than 1mA/F at 20)8. Do not use the product in an ambient atomspherecontaining waterdrops ( condensation ) ortoxic gases.Although EDLC is sealed, water droplets or toxicgases may do degradation characteristics, aleakage and corrode the lead wires and the case,which may cause a breaking of the wires.Avoid abrupt temperature changes, which may causewater droplets, resulting in product deterioration andelectrolyte leakage.9. Contact us before connecting the products inserles. 10.About vibration.A terminal blank, a terminal bend, and a creasemay occur by adding too much vibration to acapacitor.Moreover, depending on the case, an EDLC maydo degradation of the characteristic, breakage, anda leakage.When you become too much vibration, pleasecontact us.11.When used on a double sided printed circuitboard, do not overlap the wiring patterns on themounted part .A short circuit may be created by certain wiringconditions. Should the electrolyte leaks, the circuitpattern may cause a short circuit, resulting intracking or migration.12.Do not keep in high temperature and highhumidity atmospheres.Avoid high temperature or high humidity or directrays when storing capacitors.Electric Double Layer CapacitorsCAT.No.2010/2011E

ELECTRIC DOUBLE LAYER CAPACITORS®Electric Double Layer CapacitorsKeep the product in a place where thetemperature is 530 and the humidity is lowerthan 60%. Avoid an abrupt temperature change,which may cause condensation or deterioration ofthe product or liquid leakage.Do not store EDLC at a place where there is apossibility that they may get water, salt or oil spill.Do not store EDLC at place where the aircontains dense hazardous gas (hydrogen sulfide,sulfurous acid, nitrous acid, chlorine ammonia, etc.).Do not store EDLC at a place where it getsultraviolet ray or radioactive ray.13. Capacitors fitted with a relief valveThe relief valve is provided with a valve functionwith part of the case made thin to avoid explosionby increased internal pressure when the capacitoris under abnormal load such as overvoltage orreverse voltage. After activation of the relief valve,the capacitor must be replaced as it does notrestore.For the capacitors with a case relief valve,provide a void on the top of the relief valve so asnot to hamper its activation. Make a void of 2 mmor more for the product of 18 or less in diameter,and a void of 3 mm or more for the product of 20to 35 mm in diameter on the top.Mounting1. Do not overheat when soldered.Depending on the type and size of the board, theproduct may be subjected to overheat, leading toloss of airtightness. This may greatly shorten theproduct life or cause liquid leakage.ln case of a 1.6mm-thick and single side printedboard. for example, keep the following solderingconditions: temperature lower then 260, timeshorter than 5 seconds.When a board thinner than 1.6 mm or multi-layerprinted board is used, contact us.ln the case of hand soldering, the iron tiptemperature is lower than 360, time is shorterthan 3 seconds.The coin types and multilayer coin types excludingthe DZ and reflow-compatible coin types use polypropyleneas the packing material for sealing andtherefore susceptible to excessive heat. Note thatthe component body temperature shall be controlledso as not to exceed 90 including preheating.2. When soldering the capacitor to the wiringboard, do not attach the body of the capacitor tothe circuit board.If the body of the capacitor is attached directly tothe circuit board, the flux or solder can blow throughthe through holes in the circuit board, negativelyimpacting the capacitor.Moreover, the heat influence at the time of solderingcan be reduced by floating the body.3. Contact us when cleaning is necessary aftersoldering.Certain types of solvents are not compatible andmay cause damage.4. Contact us when the product is attached byadhesive bonding.Certain types of adhesives are not compatible.Paste bond partially between the product and theboard so that the product will not adhere completelyto the board.Do not raise the temperature over the guaranteedvalue while the bond is hardening.5. Heating conditions of adhesive curing ovenDuring heating of the adhesive curing oven,application of excessive heat may significantly shortenthe product life or cause liquid leakage. Control thebody temperature so as not to exceed 90 duringwork while setting the allowable atmospherictemperature below 110, and allowable heating timewithin 30 seconds.For the heating conditions deviating from the above,consult with us providing your temperature profileconditions.6. Be careful not to apply an excessive force tothe capacitor body, terminals or lead wires.Mount the capacitor while making sure that theterminal spacing of the capacitor and the spacingof the holes in the printed wiring board are aligned.lf the capacitor body is subjected to stress suchas grabbing, falling, bend, pushing or twisting aftermounted, its terminals may come off, leading toopen, short or liquid leakage.Other cautions1. Emergency procedureslf the EDLC overheats or starts to smell,immediately switch off the units main power supplyto stop operation.Keep your face and hands away from the EDLC,since the temperature may be high enough to causethe EDLC to ignite and burn.2. Periodical inspections should be establishedfor the EDLC used in industrial appliances.The following items should be checked:Appearance : Check if there is leakage.Electronic performance : Check the leakagecurrent, the electrostatic, the internal resistance andother items described in the catalog or the productspecifications.3. Disposing of EDLC.Punch a hole or crush the EDLC (to preventexplosion) before incineration at approved facility.If they are not to be incinerated, bring them to aprofessional industrial waste disposal company.4.Other notes.PIease refer to the following literature for anythingnot described in the product specifications or thecatalog.

®1 Description of Electric Double LayerCapacitor1-1 Basic ConceptsGenerally capacitors are constructed with a dielectricplaced between opposed electrodes, functioning ascapacitors by accumulating charges in the dielectricmaterial. Aluminum electrolytic and tantalum electrolyticcapacitors, for example, use an aluminum oxidefilm and a tantalum oxide film as the dielectric,respectively.On the other hand, Electric Double Layer Capacitorshave no visible dielectric in a general sense but utilizethe state referred to as the electric double layer, whichis developed naturally on the interface betweensubstances, as the function of dielectric.1-2 Operating PrincipleThe Electric Double Layer represents the state inwhich positive and negative charges exist at a veryshort distance on the boundary where contact occursbetween two different substances (e.g. solid andliquid). By externally applying a voltage below acertain voltage to the boundary, higher charges canbe accumulated. Accordingly, charge and dischargeof electric double layer capacitors utilize adsorptionand desorption of ions to the ionic adsorption layer(Electric Double Layer) formed on the electrodesurface of the activated carbon used for electrodes.ElectrolyteELECTRIC DOUBLELAYER CAPACITORSTECHNICAL NOTEApplying DC voltage externally across the electrodesof the Electric Double Layer allows almost no passageof current up to a certain voltage, exhibiting acondition like insulation.However, the application of voltages exceeding thecertain voltage causes electrolysis to occur in theelectrolyte, resulting in abrupt passage of current.This voltage determines the resistance of voltage ofan Electric Double Layer Capacitor. We use anorganic electrolyte and its standard electrolysis occursat the voltage of about 2.53V.1-3 Advantages and Disadvantages of ElectricDouble Layer Capacitor[Advantages](1) Small size and capacitance in farads (F) availableby utilizing the activated carbon electrode with alarge surface area(2) No special charging circuit and constrains duringdischarge are required.(3) No effect on the life through overcharging andoverdischarging(4) Environmentally clean energy[Disadvantage](1) The life is limited due to the use of electrolyte.(2) Series connection is required when used with alow resistance of voltage at a high voltage.(3) Cannot be used in AC circuits due to high internalresistance unlike aluminum electrolytic capacitors.ActivatedcarbonActivatedcarbonChargeDischargeFig.1 Schematic of Principle of Electric Double Layer CapacitorElectric Double Layer CapacitorsTECHNICAL NOTECAT.No.2010/2011E

TECHNICAL NOTE1-4 Construction of DYNACAPThe basic cell construction of the DB, DBN, DX,DXJ, DH, DK, DBJ, DC, DCK, DS, and DSK seriesis similar to that of coin-type batteries as shown inFig.2. DYNACAP contains a single cell or two to threecells stacked in series.Since these series have a large electrode-to-electrodedistance and a small electrode area exhibiting a largeinternal resistance, they are suitable for the memorybackup application that involves microcurrentdischarge.The cylindrical cell construction as seen in the DZ andDZN series has the construction similar to that ofaluminum electrolytic capacitors as shown in Fig.3.Gasket Electrolyte CapELECTRIC DOUBLELAYER CAPACITORSThese series have a small electrode-to-electrodedistance, allowing a large electrode area because ofthe winding structure. This decreases the internalresistance, which is primary suitable for applicationsrequiring high-power such as motor drive and LEDlighting that need high currents.2 Description of Life ExpectancyGenerally, the life of Electric Double Layer Capacitorsis largely affected by the ambient temperature.The expected life is approximated by the equation asshown below:Where,Expected lifetime at temperature TLifetime at temperatureExpected working temperatureUpper category temperature®Activated carbonelectrodeSeparatorCaseNote that the above equation does not cover chargeand discharge.

®3 Calculation Method of Discharge Time3-1 Approximating the Discharge Time of BasicConstant Current DischargeThe discharge time at the constant current of acapacitor can be calculated by the followingequation.t = (CΔV)/IWhere,t : Discharge time (sec.)C : Capacitor capacitance (F)ΔV : Working voltage range (V)I : Discharge current (A)ELECTRIC DOUBLELAYER CAPACITORSAs an example, we calculate the discharge time whena capacitor of the DB series 5.5V 1F is charged with5V and discharged to 3V at a constant current of 1mA. Since the working voltage range ΔV is 2Vfrom 5 3V, t = (1F2V)/0.001A from the aboveequation, and the discharge time can be calculatedas 2,000 seconds (about 33 minutes). Note thatthe actual discharge time may be different becausethis equation does not cover the effect of theself-discharge and the IR drop by internal resistancedescribed below.3-2 Effect of Self-discharge at MicrocurrentsWhen backup is made by discharge with a microcurrentbelow some µA especially for the memorybackup application and the like, the discharge timemust be determined while taking into account the selfdischargeas shown in Fig.4.The value closer to the actual discharge curve isobtained by adding the voltage drop through the selfdischargedetermined from the voltage retentioncharacteristic test to the discharge curve given bycalculation.Note that the value of self-discharge varies bythe charge time, charging current and an ambienttemperature.TECHNICAL NOTE3-3 Effect of IR Drop at Large CurrentsWhen a large Current discharge and a capacitor witha high internal resistance are used, the effect of IRdrop by the product of the internal resistance and thecurrent must be considered as shown in Fig.5.When a large current is required in a very short time,or a large instantaneous current flows at the start ofdischarge, the voltage drop indicated with ΔV1 counts.However, when the discharge continues as it is, thedischarge curve indicates in a manner showing a slowdiffusion and then keeps a constant straight line.We also make calculation including ΔV2 of theintersection extending from the initial discharge andthe discharge straight line section including thediffusion curve when indicating the DC internalresistance.VoltageEV2ChargeDischargeFig.5 Example of Discharge Curve involving IR DropDue to IR drop, the shape of the discharge curvevaries by the internal resistance and ambienttemperature for each series.V1Discharge curve given by calculationVoltageActual discharge curveTimeFig.4 Example of Discharge Curve involving Self-DischargeElectric Double Layer CapacitorsTECHNICAL NOTECAT.No.2010/2011E
