Würth Elektronik WE-CMB Series Common Mode Choke - 5A

The Würth Elektronik WE-CMB Series Common Mode Choke is engineered to deliver exceptional performance in suppressing electromagnetic interference (EMI). This high-quality component is designed to achieve outstanding attenuation of asymmetric interferences, even within low-frequency ranges, making it a crucial element for ensuring signal integrity and compliance with EMC standards. Its development focused on minimising parasitic effects, a key factor in enhancing overall circuit performance.

Featuring an optimised core-to-winding ratio, this choke can handle very high currents while maintaining a compact footprint. The carefully selected wire gauge contributes to low heating during operation, improving efficiency and reliability. A significant advantage is its broadband screening capability, achieved through a specialised low-capacitance winding technique. This results in a highly effective barrier against a wide spectrum of electrical noise.

With a robust construction, the choke operates reliably across a wide temperature range from -40°C to +125°C. Its very compact design allows for integration into space-constrained applications without compromising on current-handling capacity or performance. This makes it an ideal solution for modern, dense electronic assemblies where both size and power are critical considerations.

Key Features & Applications

This common mode choke is perfectly suited for demanding environments such as power management systems and motor drive controls, where stable and clean power delivery is essential. Its ability to provide high interference compression at low frequencies ensures smoother operation and protects sensitive components from disruptive noise. For unique project requirements, custom designs are available upon request, offering tailored solutions for specific engineering challenges.
