HF24H / 24V This is a common-mode choke coil for noise prevention with windings on separated
bobbins on a double-closed-magnetic-circuit ferrite core (see illustration) to ensure a higher inductance
with a smaller size and a high impedance at high frequencies with compact size and low leakage flux.
APPLICATIONS:
• For line filter of switching power supplies
• Eliminates incoming / leaking noise of TVs,
VTRs/VCRs and audio equipment
• For OA equipment, communications
equipment and other electronic devices
