434 Series - OBSOLETE - SlimLine 0603 Very Fast-Acting Thin-Film Fuse

434
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:

  • The SlimLine 0603 fuse is an extremely small, low profile design (0603 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 applications.
