Power Line Chokes

TDK EPCOS Power Line Chokes offer a rated voltage of 250V_AC, current-compensated ring/frame core double choke construction, wide inductance ranges, and high inductance with low resistance. The power line chokes are used in applications that involve the suppression of common-mode interferences, electronic ballasts in lamps, and switch-mode power supplies.
