High Performance K Series RFI Line Filters for SMPS Emission Control
SK Series
UL Recognized
CSA Certified
VDE Approved

SK Series
• Designed to reduce conducted noise to
acceptable limits for equipment that must comply
with FCC / EN specifications
• Utilizes 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
those with switching power supplies
• ESK6C and VSK6C incorporate separate ground
circuit inductor to isolate the equipment chassis
from power line ground at RF frequencies
Specifications
