INDUCTORS / BEADS
SLF Series
APPLICATIONS
Portable telephones, computers, hard disk drives and other electronic equipment.
SMD Power Inductors
OUTLINE
SLF series is designed for low profile type with low Rdc and large current.
Its magnetic shielded type is suitable for high-density mounting and flat bottom surface allows for
reliable mounting onto the board.
Soldering conditions can be easily confirmed when mounting onto the board.
This series also provides customers with embossed carrier type packaging for automatic mounting
machines.
