Littelfuse offers the NANO² fuse series in both fast acting and slow blow options.
The Littelfuse NANO² Slo-Blo® fuse 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.
The Littelfuse NANO²® SMF Fuse is a very small, Wire-in-Air (WIA) square shape surface mount fuse which is very suitable for the secondary side circuit over-current protection applications and is designed for PCB using surface mount technology.
