SK Series
Smallest, Lowest-Cost
RFI Power Line Filters
for SMPS Emission Control
UL Recognized
CSA Certified
VDE Approved
SKSeries – 3, 6 & 10 Amp Models
This series of RFIfilters was designed to reduce
conducted noise to acceptable limits for equipment that
must comply with the FCCspecifications in the USA and
CISPR specifications in Europe.
The SK (Super K) series filters use significantly higher
element values than the general purpose Kseries, 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 VDEportable equipment and (120 Volt)
UL 544 nonpatient medical equipment.
