Leaded Power Chokes DMI Series
DMI Series
DMI 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.
