SMD Shielded Power Inductors - SLF Series
SLF Series
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 machine.
Features
RoHS compliant
Low resistance and high rated currents
Applications
Portable telephones
Computers
Hard disk drives and other electronic devices
