449 Series Fuse
Description
The lead free NANO2 Slo-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 NANO2 Fast-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.
