It's a board-mount fuse — cartridge style excluded — designed to protect downstream circuitry from overcurrent faults. With a breaking capacity of 35 A at the rated voltage, it can safely interrupt a fault current up to that level without rupturing or sustaining an arc — critical for DC power rails where the available short-circuit current can exceed the fuse's interrupt rating. ## Obsolete — sourcing through independent channels For existing BOM lines or repair stock, this part is available through independent surplus and broker channels. Availability is lot-specific and confirmed at the time of an RFQ — no standing stock is held. ## Footprint and board-fit details Housed in the standard 0603 SMD package (1.60 mm x 0.80 mm x 0.35 mm), it fits the common 0603 land pattern without requiring a pad spin. The low profile — 0.35 mm seated height — suits dense, multi-layer boards where component clearance is tight. The DC cold resistance is 0.205 Ohms. At 1.3 A, the I²R power dissipation is about 0.35 W — negligible for the 0603 body in still air, but worth checking if the fuse is in a confined or high-ambient spot on the board. ## Temperature range and approvals UL approved — the fuse carries UL recognition, which simplifies acceptance in UL 508A panels and other UL-listed equipment where the component-level approval avoids a system-level fuse test.","metaTitle":"Littelfuse 0603SFV125F/32-2 Fuse, 1.3A 32V Fast Blow 0603","metaDescription":"Littelfuse 0603SFV125F/32-2 SFV series fast-blow fuse, 1.3 A, 32 VDC, 35 A breaking capacity.
