**Surface Mount Fuses** NANO[2®] > Slo-Blo[®] Fuse > 452/454 Series 

## 452/454 Series Fuse 

## **RoHS PSE** ~~(_lH# <> MW @ C€~~ 

## ~~**Description**~~ 

The NANO[2®] Slo-Blo[®] fuse has enhanced inrush withstand characteristics over the NANO[2®] 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.
