On-Board Type (DC) EMI Suppression Filters (EMIFILr)
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.
s 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.
s Applications
1. Noise suppression of SW power supply, DC-DC converter
2. DC power lines in AC adapter of Portable equipment
