SK Series
This series of RFI filters was designed to reduce conducted
noise to acceptable limits for equipment that must comply
with the FCC specifications in the USA and CISPR
specifications in Europe.
The SK (Super K) series filters use significantly higher
element values than the general purpose K series, which
makes them better suited for equipment with line-to-ground
and line-to-line conducted emissions, including switch
mode power supplies.
The ESK models meet the very low leakage current
requirements of VDE portable equipment and (120 Volt)
UL 544 non-patient medical equipment.
Models ESK6C and VSK6C additionally incorporate a
separate ground-circuit inductor to isolate the equipment
chassis from power line ground at RF frequencies.
