WE-LF Common Mode Chokes for Mains Power Lines

Würth Elektronik's WE-LF and WE-LF SMT have high attenuation of common mode interferences in low and middle frequency ranges

Image of Würth Elektronik's WE-LF Common Mode Chokes for Mains Power Lines Würth Elektronik’s WE-LF and WE-LF SMT common mode chokes feature a toroidal core with sector winding and compact size. Both series have high attenuation of common mode interferences in low and middle frequency ranges. The main difference between the two series is that the WE-LF SMT are surface mount power line chokes and available in only Type SH package size. These common mode chokes are perfect for mains filter, power electronic, and SMPS applications.
