Product Details
Filter Common Mode Inductors For Suppressing Emi Noise Of
Electronic Equipment
It adopts ferrite core, double wires are wound in parallel. The low
differential mode noise signal suppresses the interference source
and is difficult to deform in the high-speed signal. Good noise
suppression countermeasures, high common mode noise suppression and
low differential mode noise signal suppression.
The common mode filter design is relatively simple, including
common mode capacitors, balun or common mode inductors. The common
mode capacitor bypasses the common mode current of the two input
lines to the ground. The common mode inductance presents a balanced
impedance, that is, the impedance in the power line and the ground
line are equal, and this impedance presents an impedance
characteristic to common mode noise.
