Description
The 434 series fast-acting surface mount fuse series is
an ultra small (0603 size) thin-ï¬lm 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 ï¬lm fuse.
Features
t 5IF4MJN-JOF
fuse is an extremely
small, low proï¬le design
(0603 chip size) utilizing
thin-ï¬lm technology to
achieve precise control of
electrical characteristics.
t 5IFMPXFSIFJHIUQSPmMF
produces a ï¬at surface for
improved performance in
pick-and-place operations
and an alternate solution
for height critical
applications.
Applications
Secondary protection for space constrained applications
such as:
