WURTH ELEKTRONIK WE-CMB Common Mode Choke 39mH 0.3A

The WURTH ELEKTRONIK WE-CMB Common Mode Choke is engineered to achieve high suppression of asymmetric interference, even at low frequency ranges. It addresses the parasitic effects often encountered with common mode chokes, significantly reducing these issues through its advanced design.

An optimised core and winding ratio enables very high currents at comparable areas while maintaining sufficient inductance. Additionally, the adjusted wire gauge ensures low heating during operation, enhancing the reliability and lifespan of the component.

Key Features

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

With dimensions of 43 mm x 33 mm x 15 mm and a lightweight profile of just 4 grams, this choke is ideal for compact electronic assemblies. The WE-CMB series is highly suited for power management and motor drive control applications, offering robust performance and efficient interference suppression where it is needed most.
