SMD Power Inductors - CPUN Series
CPUN Series
CPUN Series is designed for low RDC and ultra large current
application. Its assembly model and magnetic shielding is suitable
for high-density mounting and ultra low buzz noise. Soldering
conditions can be easily confirmed when mounting onto board.
This series also provides customers with embossed carrier type
packaging for automatic mounting machine.
