Molding Power Choke – MHCC/MHCI Series
MHCC、MHCI Series
MHCC 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.
Features
RoHS compliant
Low profile type
Shielded construction
Ultra low buzz noise due to molding construction
Applications
High density DC/DC converters
POL converters
High current VRM/VRD for notebook / Server / desktop CPUs
High speed charger
For thickness less than 1.2mm, suitable for low profile applications
e.g., Ultra thin NB/Monitor/TV/Tablet
