Yageo corporation INDUCTORS / BEADS SLF Series SMD Power Inductors APPLICATIONS Portable telephones, computers, hard disk drives and other electronic equipment. 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.
