The NANO2 449 series Slo-Blo® surface-mount Time Lag Fuse made of ceramic body with gold-plated caps. It is fully compatible with lead-free solder alloys and higher temperature profiles associated with lead-free assembly. The Slo-Blo® design has enhanced inrush withstand characteristics over the NANO² fast-acting fuse. The unique time delay feature of this fuse design helps to solve the problem of nuisance opening by accommodating inrush current that normally cause a fast-acting fuse to open.
