The TH series of single phase, ultra high performance EMI filters are designed for use in digital systems (particularly switched mode power supplies) to suppress continuous or intermittent interference from pulse signals. They are also well suited for use with low impedance loads.
TH series EMI filters incorporate a differential mode choke to improve response in this mode, and also have a low leakage current of <0.5 mA . The rated input voltage is 120/250VAC, at 50/60Hz and the EMI filters are available in current ratings from 6 Amps to 30 Amps.
A QA test of a 1 minute test voltage of 1500VAC applied line to line and line to ground is performed on each filter at manufacture. The filters also conform to climate category 25/085/21
RFI Industries offer a complete range of EMI RF filters for both Commercial and Military applications.
