Ratings and fit for the BOM
The 1206SFP800F/24-2 is a Littelfuse SFP-series board-mount fuse in a 1206 SMT package, rated 8 A at 24 VDC with a breaking capacity of 80 A at the rated voltage. The 8 A rating is the continuous current at 25°C ambient — derate for elevated temperature per the SFP series curve. The 80 A breaking capacity means the fuse safely interrupts a fault current up to that level without rupturing the package, which is adequate for most low-voltage DC power rails in telecom, industrial control, and battery-management circuits. Melting I²t is 60 A²s, and cold resistance is 0.009 Ω. The I²t value governs inrush withstand — a capacitor bank charging through this fuse must stay below the let-through energy curve to avoid nuisance opens. The low cold resistance minimises voltage drop at full load: at 8 A, the drop is about 72 mV.
Package and board integration
The surface-mount body suits reflow assembly with no special handling beyond standard solder paste volume for the pad size.
Littelfuse lists the 1206SFP800F/24-2 as obsolete. For a BOM line that requires this exact rating and package, the supply path is surplus and broker inventory; no pin-compatible drop-in replacement from Littelfuse is documented.
