EPCOS B821.C2000H Common Mode Choke

Feature & Principle

It is EPCOS through-hole common mode choke. Two groups of windings are wound on the same magnetic core. The differential mode signal generates offset magnetic field and will not be attenuated; common mode interference signal generates superposed magnetic field to form high impedance, so as to filter common mode noise. It can restrain high-frequency interference on power lines and signal cables, reduce EMC electromagnetic radiation, protect PLC, servo and other sensitive control components.
