Murata EMI Suppression Filters for AC Power Lines

Murata EMI Suppression Filters (EMIFIL®) for AC Power Lines eliminate noise entering equipment from commercial power lines or noise generated from electronic equipment. One type of EMI suppression device is a common mode choke. Two types of common mode chokes are available from Murata. Standard type suppresses general common mode noise; high frequency type is designed for suppression of common mode noise above 10MHz.

A hybrid choke coil is a high-performance EMI suppression device that can suppress both common mode noise and differential noise at the same time. It is effective in AC power supplies with active devices for a higher harmonic countermeasure, which tends to emit relatively higher differential mode noise.
