Common Mode Choke Coils(Line Filters) for AC Power Supply

Closed Magnetic Circuit Core Type HF Series

TDK common mode choke coils(line filters) are used in a wide

range of prevention of electromagnetic interference(EMI) and radio

frequency interference(RFI) from power supply lines and for pre-

vention of multifunctioning of products such as measuring equip-

ment and system equipment.

FEATURES

• Wide range of selection.

• High impedance at applicable frequency.

• High self-resonant frequency.
