Medium Power Film CapacitorsFFVE/FFVI (FFWE/FFWI RoHS Compliant)GENERAL DESCRIPTIONThe FFV capacitor is specifically designed for DC filtering,low reactive power.The series uses a non-impregnated metallizedpolypropylene or polyester dielectric, which features acontrolled self-healing process, specially treated tohave a very high dielectric strength in operating conditionsup to 105°C.PACKAGING MATERIALSelf-extinguishing plastic case (V0 = in accordancewith UL 94) filled thermosetting resin.The FFV special design gives this series a very lowlevel of stray inductance (18 nH to 40 nH).Furthermore, the performance levels of the FFVEcapacitor makes them a very interesting alternative toelectrolytic technology, because they can withstandmuch higher levels of surge voltage, very high rmscurrent ratings, and longer lifetimes.Self-extinguishing thermosetting resin (V0 = inaccordance with UL 94; I3F1 = in accordance withNF F 16-101).FFVE capacitors meet the Level 2 requirement of the fire behavior standard NF F 16-102.Check for up-to-date CV Tables athttp://www.avx.com/docs/catalogs/filmcaps.pdfDIMENSIONSAlso available withthreaded femaleconnections -M5 x 7.5mm maxTorque 2.5Nm20(0.787)– – Male ThreadedTerminal CodeM8LABEL5 (0.197)H±1(0.039)1.0(0.039)JE or 7XFemale ThreadedM5x7.5LABEL5 (0.197)H±1(0.039)Tightening Torque3 N.m max*Mounting with Thermal Interface GreaseDimensions: millimeters (inches)General Tolerance: ±0.5 (0.020)22(0.866)45±1(1.772±0.039)Ø20 (0.787)±1 (0.039)Ø16 (0.63)minPlastic CaseTinned OutputØ5.5 (0.217)0.6(0.024)Ø84(3.307) max71.7 (2.822)84.5 (3.327) max5 (0.197)71.7 (2.822)84.5 (3.327) max5 (0.197)Max Torque 8.5 N.m for M8Max Torque 2.5 N.m for M5101(3.976)ResinHOW TO ORDERFFVE4H0187K––SeriesFFVE = StandardFFVI = StandardFFWE = RoHS CompliantFFWI = RoHS Compliant170 | www.avx.comDielectric4 = Polyester6 = PolypropyleneHOT SPOT CALCULATIONSee Hot Spot Temperature, page 3.H = 300VI = 400VJ = 500VK = 600VA = 700VB = 800Vθ hot spot = θ ambient + (P d + P t ) x R thwith P d (Dielectric losses) = Q x tgδ 0Q x tgδ 0 ⇒ [ 1 ⁄2 x C n x (V peak to peak ) 2 x f ] x tgδ 0tgδ 0 (tan delta)For polypropylene, tgδ 0 = 2 x 10 -4 for frequenciesup to 1MHz and is independent of temperatures.For polyester, tgδ 0 values are shown ingraph 4 on page 3.P t (Thermal losses) = R s x (I rms ) 2where C n in Farad I rms in Ampere f in HertzV in Volt R s in Ohm θ in °CR th in °C/Wθ case = bottom center of caseVoltage CodeC = 900VL = 1000V (FFVE/FFWE)L = 1100V (FFVI/FFWI)U = 1200VN = 1900VRs(f) vs FREQUENCYFor frequency higher than 1 kHzK3.53.02.52.01.5CapacitanceCode0 + pF code0187 = 180μF0356 = 35μFetc.Rs(f) = (Rs-a) + k aH=34: a 0.20H=40: a 0.21H=51: a 0.23H=64: a 0.24CapacitanceTolerancesK = ±10%use following curveTerminal CodeJE = Female Threaded– – = Male Threaded• FFVE/FFWE – Polyester• FFVE/FFWE – Polypropylene< 1kv• FFVI/FFWI7X = Female ThreadedJ7 = Male Threaded• FFVE/FFWE – Polypropylene≥ 1kv1.01 10 100 1000Frequency (kHz)
