EC Series

High Performance Compact RFI Power Line Filters with IEC Connectors

UL Recognized
CSA Certified
VDE Approved

Catalog Data Sheet

EC Series

The EC series RFI power line filters provide the highest attenuation of any standard filter available in a package size limited by the dimensions of the integral IEC connector. These filters combine high common-mode inductance with high differential-mode capacitance and minimal parasitic elements, for effective attenuation of line-to-ground and line-to-line noise across the frequency range.

Performance and applications are similar to those of the ED series, but with higher differential-mode performance in most applications, due to an additional capacitor on the load side.
