WE-LF Radial THT & WE-LF SMD Common Mode Chokes

Würth Elektronik WE-LF Radial THT and WE-LF SMD Common Mode Chokes feature a toroidal core with sector winding and a compact size. These chokes have high attenuation of common-mode interferences in low- and middle-frequency ranges. These chokes are broken down into the WE-LF series, which features a four-pin housing, and the WE-LF SMT series, which offers surface-mount power line chokes and is available in only a type SH package size. Würth Elektronik WE-LF Common Mode Chokes are ideal for mains filters, power electronics, and SMPS applications.
