Common Mode Choke Coils (for <strong>DC</strong> Line) PLT09H Series<br />
PLT09H series is a common mode choke coil for <strong>DC</strong><br />
lines. It is effective against the common mode noise<br />
that can cause radiative noise in power supply lines<br />
and interface lines. The additional normal mode<br />
inductance enables high suppression effect to<br />
radiation noise.<br />
