Surface Mount Fuses

NANO^2®> Slo-Blo^®> 449 Series

449 Series Fuse

Description

The lead free NANO²Slo-Blo^®fuse is RoHS compliant,

Halogen Free and 100% lead-free. This product 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 NANO²Fast-Acting Fuse. The unique

time delay feature of this fuse design helps solve the

problem of nuisance “opening” by accommodating inrush

currents that normally cause a fast-acting fuse to open.
