COMMON MODE CHOKEExample of Application with FINEMET® Common Mode Choke
Common Mode Noise Suppression in Motor Drive Circuit
- With high impedance in wide frequency band, common mode choke made of nanocrystalline soft magnetic material FINEMET® realizes high noise suppression effect.
- FINEMET® common mode choke with high impedance contributes to size and weight reduction of EMC/EMI components.
- Suppressing common mode noise will decrease bearing currents, that contributes to long lifetime of motors.
