The fast-blow response means it clears quickly on a hard short, before the downstream silicon sees the full fault energy. Rated 500 mA continuous with a 50 A interrupting capacity at 32 VDC, this fuse can safely break a fault up to 50 A without arcing through the 0603 package — that is the UL-certified breaking capacity. The 0.0093 melting I²t tells you the energy needed to open the element; for a 500 mA fuse this is low, so it coordinates well with a TVS diode or a series resistor that absorbs the let-through. ## Footprint and board integration Housed in the standard 0603 (1608 metric) chip package, the fuse measures 0.063\" x 0.031\" x 0.014\" (1.60 mm x 0.80 mm x 0.35 mm) — the same footprint as a common 0603 resistor or capacitor, so no special pad geometry is needed. The DC cold resistance of 0.86 Ohms means the fuse drops about 0.43 V at rated current — factor that into the rail budget if the load is sensitive to supply droop. Surface-mount reflow soldering follows the standard 0603 profile; the tape-and-reel packaging (Cut Tape also available) suits pick-and-place assembly. ## Lifecycle reality — obsolete, sourced on request Littelfuse has marked the 0603SFV050F/32-2 as obsolete. For a BOM line that still calls out this exact fuse, the supply path runs through independent distribution — we source it against an RFQ, confirming availability and pricing at quote time. The UL approval and the full spec trace remain valid for the existing stock.","metaTitle":"Littelfuse 0603SFV050F/32-2 Fast-Blow Fuse, 500 mA, 32 VDC","metaDescription":"Littelfuse 0603SFV050F/32-2 SFV series fast-blow fuse, 500 mA, 32 VDC, 50 A breaking capacity, 0603 SMD.
