Product Overview The T22148-1.8mH Toroidal Inductor is a common mode choke engineered for noise suppression and electromagnetic interference (EMI) filtering in switching power supplies (SMPS) and other power electronic applications. Built around a toroidal magnetic core with enameled copper wire windings, this inductor is designed to attenuate common-mode noise and help improve electromagnetic compatibility (EMC) in electronic circuits. Its compact toroidal construction makes
