Allied Electronics, Inc. Datasheets for EMI Filters and RFI Filters

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals of unwanted noise by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.

K Series RFI filters are general-purpose filters which provide line-to-line filtering in addition to normal line-to-ground attenuation of RFI. Particularly suited where pulsed, continuous and/or intermittent RF interference is present...
R Series RFI filters are premium performance dual stage filters suited for low impedance loads — particularly suited where pulsed, continuous and/or intermittent RF interference is present in your application.
The 849 Series are two-stage filters to be used when equipment impedance at RF frequency is low.
The 850 Series is a two-stage filter that provides high insertion loss for both line-to-line and line-to-ground throughout the frequency range.
The 851 Series of general-purpose single-stage filters are designed to economically suppress line-to-ground (common mode) interference and built to meet or exceed most international safety standards and requirements.
The A Series 3-phase filters are designed for 3-phase, 4-wire, WYE applications providing filtering in each of the three lines plus the neutral and ground line. These standard, high performance...
The DA Series filters were designed as general-purpose line filters for DC applications up to 125 VDC. They are compact with a 3-pin inlet connector. They are available in 3,...
The EEA Series are a new generation of compact RFI filters with IEC socket. Totally new design in both the internal structure and manufacturing process make this new series cost-effective...
