D-Core EMC Power Chokes

TDK D-Core EMC Power Chokes offer a 250VAC rated voltage, 3.3mH to 100mH inductance range, and 4.6A maximum rated current. These chokes feature high resonance frequency due to 2-section winding, low leakage due to closed core shape, high pulse strength, and low whirring noise. Construction of these D core chokes includes a current-compensated double choke, closed rectangular ferrite core, and closed plastic coil former that is UL 94V-0 rated. TDK D Core Chokes are ideal for suppressing common-mode interferences.
