LF SERIES

High Performance Low Leakage Switch Mode EMI Filter

LF Series section filters offer enhanced differential mode (L/L) and common mode (L/G) insertion loss for applications subject to the conducted limits of FCC or CISPR/EN specifications while maintaining low ground leakage current.

The LF Series filter can function as a stand alone filter for switch mode applications or in conjunction with the power supply's internal EMI filter.

Available with a wide range of current ratings, the LF Series also offers a "B" circuit option to increase common mode (L/G) insertion loss (see Filter Order Information).
