A Common-Mode Choke is an electronic component designed to filter out common-mode noise and electromagnetic interference (EMI) from electrical signals in a circuit. It consists of a coil wound around a magnetic core and is typically used in power lines, signal lines, or data cables.

• Function: The choke allows differential signals (desired signals) to pass through while blocking or attenuating common-mode noise (interference that affects both conductors equally).
• Application: It is commonly used in power supplies, telecommunications, audio equipment, and industrial machinery to improve signal integrity and ensure compliance with electromagnetic compatibility (EMC) regulations.
• Design: The component is often used in both high- and low-frequency applications to reduce EMI and ensure that the system operates efficiently without disrupting other nearby electronic devices.

Common-mode chokes are vital for maintaining the stability and reliability of electronic systems by filtering unwanted noise and protecting against signal degradation.
