The 443LC Series NANO²® fuse is a 4012 footprint, Slo Blo surface mount fuse which provides overcurrent protection for applications with working voltage up to 277VAC.

Its high I2t provides superior surge withstand capability for its small footprint. This can therefore be used on applications where board space is a limitation, without worrying of any nuisance failures due to surge/pulse current and voltages in the application, or where larger sized solutions are previously being used.

Features:

  • 280VAC-rated fuse in a relatively small footprint of 10mm x 3mm (sq)
  • Slo Blo fuse type with relatively high I2t values
  • RoHS compliant, Halogen Free
  • Surface mount type fuse

Benefits:

  • Option for applications with working voltage up to 277VAC
  • With superior surge withstand capability, considering its size, and is suited for applications where surge current/voltages are inherent and board space is a constraint
  • Compliant to global EHS standards
  • Fully compatible with lead free solder alloys and higher temperature profiles associated with high volume, lead-free assembly SMD processes

Applications:

  • Lighting Ballast
  • LED Driver Boards
  • LED Dimmer Controllers
  • 3-Phase power supplies
  • Utility connected  appliances and equipment rated at 277V AC
