HF28H / 28V 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
