SURFACE MOUNT FUSES
SUBMINIATURE SURFACE MOUNT
NANO
2 SMF Slo-Blo Type Fuse
The very small NANO2 Fuse with time delay performance
characteristics. 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.
