Common Mode Choke Coils (for DC Line) PLT09H Series

PLT09H series is a common mode choke coil for DC

lines. It is effective against the common mode noise

that can cause radiative noise in power supply lines

and interface lines. The additional normal mode

inductance enables high suppression effect to

radiation noise.

c Features

1. This is a wide frequency range type, applicable in

applications ranging from a few MHz to several

100MHz.

2. It features a low-profile design.

c Applications

1. Noise suppression of SW power supply, DC-DC converter

2. DC power lines in AC adapter of Portable equipment
