Molding Power Inductors – BMMN Series
BMMN Series
BMMN Series is designed for low profile type 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.
