Description
The 434 series fast-acting surface mount fuse series is
an ultra small (0603 size) thin-film device designed for
secondary protection of circuits used in space constrained
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
tꢀ 5IFꢀ4MJN-JOFꢀꢁꢂꢁꢃꢀ
fuse is an extremely
tꢀ 5IFꢀMPXFSꢀIFJHIUꢀQSPmMFꢀ
produces a flat surface for
improved performance in
pick-and-place operations
and an alternate solution
for height critical
small, low profile design
(0603 chip size) utilizing
thin-film technology to
achieve precise control of
electrical characteristics.
