Common Mode Choke Coils(Line Filters) for AC Power Supply
Conformity to RoHS Directive
Toroidal Core Type TF 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.

∗ Handling power=(Inductance value)× (Current)2. It is possible to design within the range below this value.
[Example] The coil for 2A can make even the inductance of 2.5mH or less a product for handling power 10.
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
• All specifications are subject to change without notice.
