Product details

Ratings and fit for the BOM line

The 0603SFS200F/32-2: Rated 2 A at 32 V DC with a 50 A interrupting capacity — this fuse clears a short before the trace or cable insulation reaches its thermal limit in a 32 V DC rail. Slow-blow response (0.32 A²s melting I²t) handles inrush from a capacitive or inductive load without nuisance opens — the element absorbs the surge energy without fatiguing.

Package and reflow consideration

0603 (1608 metric) footprint, surface-mount — the 0.031-inch (0.80 mm) height keeps the fuse clear of the pick-and-place nozzle and the reflow profile matches standard SAC305 solder paste.

UL recognized — the fuse carries the same safety agency mark as the original production, so replacement parts from surplus stock maintain the same regulatory acceptance.

Frequently asked questions

What is the melting I²t and why does it matter?

The melting I²t is 0.32 A²s. This value determines how much energy the fuse absorbs before opening — critical for sizing the fuse to survive the inrush pulse of a capacitor bank or motor start without nuisance tripping.
