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-to-
ground 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 nonpatient medical equipment.
