applications such as hand-held portable electronic devices.
For RoHS compliant and lead-free design, please refer to
the Littelfuse 467 series thin film fuse.
Features
fuse is an extremely
small, low profile design
(0603 chip size) utilizing
thin-film technology to
achieve precise control of
electrical characteristics.
Applications
Secondary protection for space constrained applications
such as:
produces a flat surface for
improved performance in
pick-and-place operations
and an alternate solution
for height critical
applications.
