K Series

General Purpose RFI Power Line Filters - Ideal for High Impedance Load

UL Recognized
CSA Certified
VDE Approved

Catalog Data Sheet

K Series

The K series RFI power line filters are general purpose common-mode and differential-mode filters. They are effective in the control of line-to-line as well as line-toground RFI interference. The K series RFI filters are particularly suited in applications where pulsed, continuous and/or intermittent RFI interference is present. The EK models meet the very low leakage current requirements of VDE portable equipment, and (120 Volt) UL544 non-patient medical equipment.
