WE-CMB Common Mode Power Line Inductors (Chokes)

Würth Elektronik WE-CMB Common Mode Power Line Inductors (Chokes) feature a compact design that delivers high suppression of asymmetric interferences, even at low-frequency ranges. In addition, these inductors provide broadband screening due to a low capacitance winding technique. Würth Elektronik WE-CMB Common Mode, Power Line Inductors, are ideal for power electronics and suppressing common-mode noises. Parasitics can have a significant effect on the noise attenuation and current rating of a common mode filter. Würth designed the WE-CMB series for minimal parasitic effects over its useful frequency bandwidth so it does what it is designed to do - get rid of the noise.
