High-performance WE-CMB series common mode choke for suppressing asymmetric EMI. Compact design, high current rating, -40°C to 125°C operating range.
The WURTH ELEKTRONIK WE-CMB Series Common Mode Choke is a premium electronic component engineered for superior electromagnetic interference suppression. It is designed to effectively reduce asymmetric interference, even within challenging low-frequency ranges. Its development focused critically on minimising parasitic effects, a common concern with common mode chokes, resulting in a highly optimised and reliable performance.
This choke features an ideal core-to-winding ratio, enabling it to handle very high currents within a compact footprint while maintaining sufficient inductance. The carefully selected wire gauge contributes to minimal resistive heating during operation, ensuring efficiency and longevity. Its innovative low-capacitance winding technique provides exceptional broadband screening, making it an excellent choice for noise-sensitive applications.
The series boasts a very compact design, allowing for significant space savings on PCBs without compromising on current handling or performance. It delivers the highest possible current ratings for its small size and offers high compression of asymmetric interference across a broad frequency spectrum. For specialised requirements, custom design solutions are available upon request, providing tailored EMC compliance.
Constructed for durability, the WE-CMB choke operates reliably across an extensive temperature range from -40°C to +125°C, making it suitable for demanding industrial, automotive, and telecommunications environments. Its robust construction and precise engineering ensure stable performance in filtering and noise suppression circuits, protecting sensitive electronic equipment from disruptive electromagnetic noise.
