WURTH ELEKTRONIK WE-CMB Common Mode Choke 20mH 0.5A

The WURTH ELEKTRONIK WE-CMB Common Mode Choke is engineered to achieve high suppression of asymmetric interferences, even at low frequency ranges. During its development, significant focus was placed on reducing parasitic effects, which are a common challenge when using common mode chokes. This results in a component that delivers reliable interference compression across the board.

Featuring an optimised core and winding ratio, the WE-CMB series enables high currents at comparable physical sizes while maintaining sufficient inductance. Additionally, the adjusted wire gauge ensures low heating during operation, enhancing the component's longevity and performance stability.

Key Features

• Broadband screening achieved through a low capacitance winding technique
• Very compact design suitable for space-constrained applications
• High interference compression for asymmetric interference rates, even at low frequency ranges
• Wide operating temperature range from -40°C to +125°C

With physical dimensions of 43 mm x 33 mm x 15 mm and a lightweight profile of just 7.4 grams, this common mode choke is perfectly suited for dense circuit board layouts where space and thermal management are critical.
