TDK EP21 common-mode chokes deliver up to 35 A for DC-DC converters
TDK's new EP21 series of flat-wire double chokes enables robust common-mode filtering in DC-DC converters and low-voltage EMC circuits, handling currents up to 35 A without derating to 70°C. The compact SMD package minimizes board space while improving mechanical reliability, with inductance options from 160 to 640 µH.
