WURTH ELEKTRONIK WE-CMB Common Mode Choke 1.3mH 20A

The WURTH ELEKTRONIK WE-CMB Common Mode Choke is engineered to achieve high suppression of asymmetric interferences, even at low frequency ranges. During the development of the WE-CMB series, reducing parasitic effects was a primary focus, ensuring reliable performance in demanding electronic environments.

Featuring an optimised core-to-winding ratio, this choke enables very high currents at comparable areas while maintaining sufficient inductance. The adjusted wire gauge effectively realises low heating during operation. Additionally, the low capacitance winding technique provides broadband screening, making it highly efficient at compressing asymmetric interference rates.

Designed with a very compact footprint, this component delivers high current capacity within a small size. It operates reliably within a temperature range of -40°C to +125°C. With an inductance of 1.3mH and a DC current rating of 20A, it is well-suited for demanding circuits.
