common mode inductor
Common-mode inductor (Common mode Choke), also known as the Common mode Choke coil, used in the switch power filter in the Common mode of computer electromagnetic interference signals. In the board design, common-mode inductor is also plays a role of EMI filter, used to suppress the signal produced by electromagnetic radiation emission outward.
Common mode Choke is also called Common mode Choke. Characteristics: high initial permeability, in the geomagnetic field with large impedance and insertion loss, if the interference has excellent inhibition, in a wider frequency range presents no resonance insertion loss characteristics. High initial magnetic permeability: 5-20 times of ferrite, thus having greater insertion loss and much greater inhibition of conduction interference than ferrite. High saturation magnetic induction: 2 to 3 times higher than ferrite. It is not easy to magnetize to saturation in the case of strong current interference. L excellent temperature stability, high Curie temperature, in situations where there are large temperature fluctuations, the performance of the alloy significantly lower rate of ferrite, with excellent stability, and the change of performance close to the line.
