Token SMD Choke Coils Common Mode - TCB4F Series are primarily designed for choking power lines and conform to the RoHS directive and Lead-free. SMD Choke Coils feature with ultra-compact size, wide inductance selection, and low-resistance coils. SMD Choke Coils can be customed designs and tighter tolerances available on request. Application of SMD Choke Coils specific designs also available including different inductance values and Q specifications adjusted to frequency requirements.
  • Featureschoke coils
    －Pair wire coil for high stability.
  • Applications
    －Double Balance Mixers, Broad-Band Transformers;
    －Impedance Transformers, Balun Transformers, etc..
