Surface Mount Fuses

Subminiature Surface Mount

NANO^2®Slo-Blo^®Fuse 452/454 Series

The NANO²Slo-Blo fuse 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 accommo-

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