Product details

3.5 A at 32 VDC — the SFP Slo-Blo fuse in 1206

The Littelfuse 1206SFP350F/32-2 is a 3.5 A, 32 VDC board-mount fuse from the SFP series, a Slo-Blo flat-pack family designed for overcurrent protection in space-constrained circuits. Its 50 A breaking capacity at the rated voltage means it can safely interrupt a short-circuit fault up to that current without rupturing or arcing — a critical spec for secondary-side protection in DC power rails.

Melting I²t and cold resistance — inrush and drop budget

With a melting I²t of 1.84, this fuse tolerates brief inrush pulses common in capacitor-charging or motor-start circuits without nuisance opening — a 3.5 A Slo-Blo holds longer through a start surge than a fast-acting type at the same current.
