Molding Power Choke – MHSC Series
MHSC Series
MHSC series is designed for low profile type with low DCR and ultra
large current, especially for height limited boards. 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 board. This series also provides customers with embossed carrier
type packaging for automatic mounting machine.
Features
RoHS compliant
Ultra low profile on board
Shielded construction
Ultra low buzz noise due to molding construction
Applications
High density DC/DC converter in height limited board
POL converters
High current VRM/VDR for notebook / server / desktop CPU
High current DC/DC converter in distributed power system
High speed charger
