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.
