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.
DM Dust Choke Coils
Chemi-Con DM Dust Choke Coils offer a 3A to 10A maximum DC current range, 760µH maximum inductance rating, and a DC resistance of 25mΩ to 72mΩ. These coils exhibit excellent DC superimposition characteristics and achieve significant miniaturization. DM coils feature a great reduction of core loss, enabling low temperature rise at high frequency ratings. Chemi-Con DM Dust Choke Coils are ideal for PFC use in switching-mode power supplies.
