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 at 32VDC
  • Small size with current ratings of 0.25 to 5.0 amperes
  • RoHS compliant, Lead-Free and Halogen-Free
  • Maximum protection of sensitive circuits as fuses are designed to open consistently in <5sec at 200% overload.
  • Enhanced Breaking Capacity, High l²t

Applications:
Secondary protection for space constrained applications such as:

  • Cell phones
  • Battery packs
  • Digital cameras
  • DVD players
  • Hard disk drives
