YAGEO CORPORATION
SMD INDUCTOR / BEADS
SMD Power Inductors
SLF Series
fEATURES
• Low resistance and high currents
Designed for low - profile type with low Rdc and large current.
The magnetic shielded type is suitable for high density mounting.
Flat bottom surface allows for reliable mounting onto the board.
Soldering conditions can be easily confirmed when mounting onto the board.
Provide with embossed carrier type packaging for automatic mounting machine.

• Note: YAGEO will start to release SLF Series inductors with lead-free terminals which meet
SONY SS-00259's criteria for lead-free product in Q2 of 2004, and YAGEO Internal No
will be changed to “N” as identification. Ex. SLF0628T-4R7M-N
