Leaded Power Chokes DMI Series
DMI Series
DIM series is designed with low RDC and ultra large current. Its
molded magnetic shielded type is suitable for high-density mounting
and ultra low buzz noise. Soldering conditions can be easily confirmed
when mounting onto the board. This series also Provides customers
with embossed carrier type packaging for automatic mounting
machine.
