Power Inductors & Chokes

TDK Power Inductors and Chokes feature a temperature range up to +150°C, low DC resistance, ferrite core construction, AEC-Q200 qualification, and a wide inductance value range. These power inductors are utilized in many applications, including multimedia, automotive electronics, industrial electronics, consumer electronics, DC/DC converters, and telecommunications. TDK Power Line Chokes offer a rated voltage of 250V_AC, current-compensated ring core, and frame core double choke construction, wide inductance ranges, high inductance with low resistance, and more. 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.
