Obsolete — sourcing path for this Littelfuse 0603 fuse
The 0603SFP100F/32-2: Rated 1 A at 32 V DC with a 50 A interrupting capacity at rated voltage, this SFP-series fuse clears a short-circuit fault before the downstream trace vaporizes — the 0.08 A²s melting I²t gives the coordination engineer the energy to budget for let-through.
Board-fit and parametric check for the BOM line
The 0603 (1608 metric) footprint is standard — 1.60 mm x 0.81 mm — and the 0.21 Ω cold resistance means the voltage drop at 1 A is about 210 mV, which matters if the load rail is tight on headroom.
