The 435 Series are fast-acting surface mount thin-film
fuses.Their ultra-small size (0402 size) makes them ideal for
secondary protection of circuits used in space constrained
applications such as hand-held portable electronic devices.
This series is 100% lead-free and meet the requirements of
the RoHS directive. New Halogen-Free 435 Series fuses are
available–to order use the “HF” suffix. See Part Numbering
section for additional information.


Features:

  • 35A interrupt rating at32 VDC
  • Small size with currentratings of 0.25 to 5.0amperes
  • RoHS compliant, leadfree and halogen-free
  • Maximum protectionof sensitive circuitsas fuses are designedto open consistentlyin <5sec at 200%overload.
  • Enhanced BreakingCapacity, High l2t
