EMI CapabilitiesFor Maximum Design FlexibilityAmphenolAerospaceThe Amphenol ® EMI filter connector utilizes two manufacturingtechnologies to provide the user with the most cost effectiveperformance across the frequency range. (For EMP performancedata, see pages 332-336).The tubular design offers over 40 years of proven fieldreliability. All filter contacts within the connector share acommon ground plane, which is connected to the connectorshell. The pin to pin isolation is 85 dB minimum at 100 MHz.The planar design joins pins to a multi-layered ceramic,forming an array sub-assembly with a peripheral ground. Thisis connected to the connector shell via a ground spring. Pin topin capacitance is less than 50 pf with a pin-to-pin isolation of85 dB minimum at 100 MHz. Filter contacts for both designscontain either a pi passive ele ment network comprised of aferrite inductor and ceramic capacitor, or a single capacitor.ShellFilterContactAssemblyGasketTUBULAR ASSEMBLYGround PlateFor planar designs, other filter networks are available, ie.T Type, L-C Type, C-L Type and C Type. An encapsulant ofoven-cured epoxy in the rear provides:• Mechanical and thermal insulation of the ceramicelements – mechanical loading can be accomplishedwithout capaci tor damage. Pins can be bent 90° andstraightened with no damage to the filter.-3• Hermeticity (4.6 x 10 cc/sec) – prevents water fromenter ing through the rear of the connector in highhumidity envi ronments. Amphenol recommends usingmetal protection caps during cleaning operations.ShellGasketPLANAR ASSEMBLYGroundingRingOven CuredEpoxyPotting SealContact andPlanarAssembly38999III II I SJT26482 83723 III 5015Matrix 2Matrix PyleCrimp RearRelease Matrix26500 PylePrintedCircuit BoardInterfacialSealHard FacedInsertOven CuredEpoxyInterfacialSealFerriteHard FacedInsertEMI FilterTransientPi Type Tubular Contact AssemblyGround ElectrodeInternal MarginExternal MarginFerrite InductorSolder JointCeramic CapacitorHot ElectrodesSolder JointExternal MarginSolder Washeror SpringClipPi Type Planar Array AssemblyGrounding RingFerrite InductorGroundElectrodeHotElectrodeFiber OpticsHigh SpeedContactsOptionsOthersContact Amphenol Aerospace for more information at 800-678-0141 • www.amphenol-aerospace.com279
