EMC Components TF Series
Common Mode Choke Coils(Line Filters) for AC Power Supply
Toroidal Core Type
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.
RATINGS
