443LC Series - NANO²® 280VAC-Rated Surface Mount Fuses
Brand: Littelfuse, IncThe 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
- 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
