As a world leader in RFI technology, Corcom offers a wide range of power line filters, power entry modules and filtered modular jacks (RJ11-RJ45) specifically designed to help bring equipment (even those with switching power supplies) into compliance with strict FCC and International emissions standards. With hundreds of standard catalog designs, Corcom offers a wide range of solutions to problems caused by radio frequency interference. Corcom also has world-class abilities to quickly develop custom filters to solve unique RFI challenges OEM’s encounter.

Power Line RFI filter models include standard as well as low leakage designs for medical specifications; current ratings from 1 to 1200 amps, and a variety of mounting styles. Power Entry Modules include IEC inlet, with models offering fusing, switching, voltage selection and, of course, EMI-RFI filtering with a variety of mounting styles. Product performance levels vary in order to provide filtering with optimal size and price.

Corcom’s Signal Sentry™filtered modular jack is a space saving and cost effective solution to RFI problems on signal lines. Its inductive and optional capacitive elements effectively strip common mode noise from the incoming signal, and at the same time limit the signal line’s ability to radiate emissions like an antenna. Signal Sentry™ products are useful for any electronic equipment that sends or receives data on unshielded twisted pair or other multi-conductor, cabling systems. Modems, PBX’s, LAN, ISDN and local I/O interfaces that use RJ connectors are all candidates.
