The 433 series fast-acting surface mount fuse series
is a small (1206 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 466 series thin film fuse. For new designs of
7 amp please refer to Littelfuse 429 series thin film fuse.


Features:

  • The SlimLine 1206 fuse is an extremely small, low profile design (1206 chip size) utilizing thin-film technology to achieve precise control of electrical characteristics.
  • The lower height profile produces a flat surface for improved performance in pick-and-place operations and an alternate solution for height critical application.
  • Mounting pad and electrical specification are identical to the popular 429 Series specifications.
