SK Series Smallest, Lowest-Cost RFI Power Line Filters for SMPS Emission Control SK7 UL Recognized CSA Certified VDE Approved SK1 SK3 SK Series - 3, 6 & 10 Amp Models Specifications 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. Maximum leakage current, each line-to-ground @ 120 VAC 60 Hz: @ 250 VAC 50 Hz: 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-toground 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 nonpatient medical equipment.
