Allen Avionics
Allen Avionics makes precision custom-built LC noise filters including band pass filters (400 Hz to 500 MHz), high pass filters (100Hz to 1000MHz), low pass filters (50Hz to 5000MHz; 20, 200, 500, and 1000 watts), and diplexers, with applications including microwave filtering. -
Capcon International
Capcon International makes several EMI noise filters, including low pass filters and miniature sized component filters as well as microwave absorbers and other absorbative filters. Their minuature models filter either AC or DC power lines for up to 10 Amps at 50VDCW, 100VDCW, or 115VACW. Capcon also offers military grade filters. -
Coilcraft
Coilcraft makes many EMI/RFI filters including surface mount and leaded components, LC filters, and signal line filters, which work on RJ-45, RJ-15, and RJ-11 lines. Their LC filters include high and low pass models and feature less than 0.3 dB insertion loss with 50 or 75 Ohm characteristic impedance. -
DCI Digital
DCI Digital makes custom noise filters including Band Pass filters, high and low pass filters, component sized filters, and ISM filters. Also available are diplexers, with channel isolation from >39dB to >90dB. Models can be built to military specification and are used in fixed and mobile military installations with many frequencies available starting at 30MHz. -
Filtronetics
Filtronetics makes custom EMI/RFI noise filters such as bandpass, high pass, bandstop, and lowpass filters, with frequencies of >1MHz to 6GHz. They also have LC filters, diplexers, surface mount models, and ISM filters. Some applications include military and microwave filtering. -
KR Filters
KR Electronics makes custom and standard filters for commercial and military uses including Low Pass filters, high pass filters, band pass filters, LC filters, Diplexers, and surface mount filters.
