RFI Power Line Filters

Curtis Industries, the leading manufacturer of superior quality electronic and electrical components and assemblies for more that 75 years, offers a complete line of RFI power line filters designed to make equipment meet FCC/VDE requirements on conducted EMI.

Radio frequency interference (RFI) is unwanted noise generated by a wide variety of electronic and electrical devices. Governments of most industrial countries, including the United States, Canada and many European nations, have enacted guidelines on emitted RFI. Most notable are FCC docket 20780 in the United States and VDE (Verband Deutscher Electrotechniker) 0871 and 0875 in Germany. Computing devices, industrial controls, medial instrumentation, electronic games, and other electronic devices that generate unwanted radio frequency energy greater than 10 kHz must comply with these governmental and safety agency requirements.

The product design concepts, controlled assembly and testing processes at Curtis Industries ensure the highest quality RFI power line filters to help systems manufacturers meet governmental emissions and safety requirements. Computer-controlled production test equipment assures Curtis Industries customers that all electrical parameters are met on each filter shipped.
