Description
The 433 series fast-acting surface mount fuse series
is a small (1206 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 466 series thin ï¬lm fuse. For new designs of
7 amp please refer to Littelfuse 429 series thin ï¬lm fuse.
Features
t 5IF4MJN-JOF
fuse is an extremely
small, low proï¬le design
(1206 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
application.
