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.

Applications

• Compact fluorescent lamp
• Television receiver
• Radio cassette player
• PC power supply
• Monitor,audio,VCD,DCD
• UPS
• The electronic apparatus
• The noise rejection
• Induction cooker,etc.
