EMI Filter Transient - Amphenol Aerospace

EMI CapabilitiesFor Maximum Design Flexibility, ContinuedPlanar Capacitor TechnologyThe Amphenol ® EMI filter connector utilizes planar capacitortechnology to provide the user with the most reliable and costeffective performance across the frequency range.

An encapsulant of oven-cured epoxy in the rearprovides:• Mechanical and thermal insulation of the ceramicelements – mechanical loading can be accomplishedwithout capaci tor damage.• Pins can be bent 90° and straightened with no damage tothe filter.• Hermeticity (4.6 x 10 -3 cc/sec) – prevents water fromenter ing through the rear of the connector in highhumidity envi ronments.• Amphenol recommends using metal protection capsduring cleaning operations.Contact Options:• Coaxial, concentric twinax, triax and quadrax contactscan be included in arrangements of filtered contacts forsignal or power circuits (Please refer to theHigh Speed Contacts Section for High FrequencyContacts for Multi-Pin Connectors).• Filter contacts with differing cut-off frequencies can bemixed in any given insertarrangement. (ratio 100:1 typical)• Ground, insulated or filter contacts can be combinedwithin the same connector to meet unique or changingfrequency protec tion requirements.• Thermocouple contacts• Diodes or MOV for EMPShellInterfacialSealGasketWireAmphenolAerospacePLANAR ASSEMBLYGroundingRingTerminationsFerriteHard FacedInsertMethods of Wire Termination:• Solder cup - wire termination• PCB termination (Pre-tinning is available)• Solderless wrap• Amphenol ® UTS(Universal Termination System)allows crimp termination.
