An Introduction to Common Mode Chokes

Posted by Bill Dull | February 28, 2020 | 0 Comments

A choke is a magnetic inductor used to block or limit unwanted high-frequency alternating current (AC) while allowing the desired lower frequency direct current (DC) to pass through. The choke acts as a filter for the noise produced by other radio signaling devices, inverters, and unshielded equipment, thereby reducing interference in electrical and electronic devices and systems.
