Würth Elektronik WE-CMB Common Mode Choke, 110µH, 3A

The Würth Elektronik WE-CMB Common Mode Choke is engineered to deliver exceptional suppression of asymmetric interferences across a wide frequency spectrum, including the challenging low-frequency ranges. A primary focus during its development was the meticulous reduction of parasitic effects, which are often underestimated in common mode applications. This results in a component that provides reliable and clean signal integrity.

Featuring an optimised core-to-winding ratio, this choke achieves remarkably high current handling capabilities within a compact footprint, without compromising on its specified inductance. The carefully selected wire gauge contributes to minimal resistive heating during operation, enhancing both efficiency and long-term reliability. Its low capacitance winding technique enables effective broadband screening, making it an excellent choice for filtering noise in sensitive electronic circuits.

This series is distinguished by its very compact design, which allows for high-density PCB layouts while still supporting the highest possible current ratings for its size. It excels in providing high compression of asymmetric interference, even at low frequencies, ensuring stable performance for your critical applications. Custom designs are available upon request to meet specific project requirements.

Built to operate reliably in demanding environments, the choke supports a broad operating temperature range from -40°C to +125°C. Its robust construction and precise engineering make it an ideal solution for power supplies, data lines, and any application requiring effective common mode noise suppression.
