It is rated for 32 VDC continuous and can interrupt a fault current up to 50 A at that voltage — the 50 A breaking capacity covers most low-voltage DC rails in portable equipment, battery packs, and peripheral ports where the available short-circuit current stays under that ceiling. ## Melting I²t and cold resistance — the coordination parameters With a melting I²t of 0.11 A²s and a DC cold resistance of 0.101 Ohms, this fuse opens fast on a hard short but tolerates the inrush of a 100 µF capacitor charged from a 12 V rail — the energy let-through stays below the downstream silicon's I²t withstand. ## Obsolete — sourcing through independent channels Littelfuse lists the 0603SFP150F/32-2 as obsolete.","metaTitle":"0603SFP150F/32-2 Littelfuse SFP Fuse, 1.5 A, 32 V, 0603","metaDescription":"0603SFP150F/32-2 Littelfuse SFP series board mount fuse, 1.5 A, 32 VDC, 50 A breaking capacity.
