Youcan select your options for your particular interferencethreats - VHF, UHF, HF or other filter ranges, then couplewith a connector package of your choice. Or give Amphe nolyour custom shell design requirements for assistance indesigning your unique filter solution.EMI Filter connectors are intended for use in temperaturesfrom –55°C to +125°C. Attenuation will change with feedthroughcurrent and temperature.*To assure reliability, connectors may be subjected to anattenuation performance test verifying proper assembly andgrounding of the filters. Attenuation data on filter performanceis stated in reference to a 50 ohm impedancesystem in order to allow filter performance to be moreeas ily translated into real world impedances. Those interestedin determining the expected filter perfor mance in animpedance system other than 50 ohms may refer to page284 of this catalog or may contact Amphenol Aerospace forfurther assistance.It is suggested that the user analyze his systemrequire ments for EMI protection in the following areas:• Working voltage (DC or AC and Frequency)• Peak voltage• Desired attenuation at a given frequency level• Any special capacitance limitationsDefinition of Filter Contacts:MF-1HF-1VHF-1UHF-1Medium Frequency50 dB performance between 300 - 2999 KHzHigh Frequency50 dB performance between 3 - 29 MHzVery High Frequency50 dB performance between 30 - 2999 MHzUltra High Frequency50 dB performance between 300 - 2999 MHzFilter contacts can be provided in most frequencies incon tact sizes 22 or larger. Consult Amphenol Aerospacefor availability.Tubular connector designs will meet 3 amps RF currentfrom –55°C through +125°C. Planar connector designswill meet 5 amps.* More in-depth information on attenuation is available in:L-1146, General Design Guideline for EMI Filters and/orTVS (Transient Voltage Suppression) Connectors.Also for further information ask for:L-1145, How to Specify Filter Connectors.Planars, MOV’s, Tubular and Diode ContactsPlanar ArrayAssemblyCapacitor andMOV PlanarsTubular Filters andDiode ContactsContact Options• Coaxial, concentric twinax, triax and quadrax contacts can beincluded in arrangements of filtered contacts for signal or powercircuits (Please refer to the High Speed Contacts Section forHigh Frequency Contacts for Multi-Pin Connectors).• Filter contacts with differing cut-off frequencies can be mixed inany given insert arrangement. (ratio 100:1 typical)• Ground, insulated or filter contacts can be combined within thesame connector to meet unique or changing frequencyprotec tion requirements.• Thermocouple contacts• Diodes for EMPMethods of Wire Termination• Solder cup - wire termination• PCB termination (Pre-tinning is available)• Solderless wrap®• Amphenol UTS (Universal Termination System) allows crimptermination. It uses crimp insertable socket contacts oncon ductor wires. Sockets mate with filter pins within theconnector body. (Socket type M39029/57).
