T Series
The T series RFI filters provide superior common-mode and premium differential-mode attenuation, exceeded only by that of Q series filters. This remarkable performance is available for current ratings up to 20 amps in package sizes smaller than comparable EP series filters. In fact, the 10-amp T is smaller than the 6-amp EP.
These filters are a size and cost-effective choice for very noisy equipment that must meet the emission limits of FCC Parts 15 and 18 or EN55022, A-level. In some cases, these filters can even bring equipment into compliance with EN55022, B-level. This performance is accomplished with circuits that still meet the very low leakage current requirements of VDE portable equipment, and (120 Volt) UL544 non-patient medical equipment
