Product details

1 A slow-blow in a 0603 footprint

The Littelfuse 0603SFS100F/32-2 is a 1 A slow-blow board-mount fuse in the 0603 (1608 metric) package, rated for 32 VDC with a breaking capacity of 50 A at that voltage. The slow-blow response handles inrush currents without nuisance opens — the 0.093 melting I²t gives a sense of the energy needed to clear it.

This part is listed as obsolete by Littelfuse.

Package and board-fit

Surface-mount 0603 (1608 metric) — 0.063" L x 0.031" W x 0.031" H. The DC cold resistance is 0.2 Ohms, so voltage drop at rated current is about 200 mV.
