Description
General part information
0443.750 Series
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.
