EMI (Electro Magnetic Interference) suppression filter for AC

power lines eliminate noise entering equipment from

commercial power lines or noise generated from electronic

equipment.

Common mode chokes, line bypass capacitors, across the

line capacitors are generally used as AC EMI suppression

filter device. In suppressing common mode noise, common

mode chokes are most important devices. Because the

characteristics of common mode chokes influences

performance of total filter block MURATA provides two types

of common mode chokes. (Standard type, High frequency

type)

Hybrid choke coil is high performance EMI suppression

device which can suppress both common mode noise and

differential mode noise at the same time. It is effective in AC

power supplies with active device for higher harmonic

countermeasure, which tend to emit relatively higher

differential mode noise.
