Common Mode Chokes are essential components in electrical circuits that mitigate electromagnetic interference (EMI) by filtering out common mode noise. They consist of inductive coils wound on a magnetic core, which work to suppress high-frequency interference while allowing desired signals to pass through with minimal loss.

Used extensively in power supplies, communication lines, and audio equipment, these chokes enhance signal integrity and performance. Prominent manufacturers include TDK Corporation, Murata Manufacturing, and Vishay.

With their ability to cater to various industry standards and applications, Common Mode Chokes are indispensable in achieving compliance with international electromagnetic compatibility (EMC) regulations.
