Common Mode Choke Coils(Line Filters) for Signal Line
UF and TF Series
TDK’s compact type common mode choke coils are suitable for
protecting telephone circuitry from interference such as radio
broadcasts or noise conducted from the DC side of an AC adapter.
FEATURES
• Compact size and lightweight.
• High reduction over a wide range of frequencies.

SELECTION CHART
∗ 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.
