433 Series Fuse
Description
The 433 series fast-acting surface mount fuse series
is a small (1206 size) thin-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 lm fuse. For new designs of
7 amp please refer to Littelfuse 429 series thin lm fuse.
