Würth Elektronik Common Mode Choke 1.8mH 14A, 1.8mH

The Würth Elektronik WE-CMB Series Common Mode Choke is a high-performance component engineered to effectively suppress electromagnetic interference (EMI) in electronic circuits. Its core design delivers outstanding broadband screening and interference compression, making it a vital solution for ensuring signal integrity and compliance with EMC regulations.

A standout feature of this series is its ability to achieve high suppression of asymmetric interferences, even within the challenging low-frequency range. The development of the WE-CMB series focused critically on minimising parasitic effects, a common issue with common mode chokes, resulting in a component with superior performance and reliability.

The choke boasts an optimised core-to-winding ratio, enabling it to handle very high currents (up to 14A) while maintaining a compact footprint. This efficient design, combined with an adjusted wire gauge, results in low operational heating, enhancing both safety and longevity. The advanced low-capacitance winding technique is key to its excellent broadband screening capabilities.
