SFP series board mount fuse, 1206 (3216 Metric) package, 1 A, 63 V DC, 50 A breaking capacity, 0.11 melting I²t, 0.34 Ohms DC cold resistance.","salesMarkdown":"## What the ratings mean for your protection design The 1206SFP100F/63-2 is a 1 A, 63 V DC rated board-mount fuse in the Littelfuse SFP series, housed in a standard 1206 (3216 Metric) surface-mount package. Its 50 A breaking capacity at the rated voltage means it can safely interrupt a fault current up to 50 A without arcing or rupturing the ceramic body — critical for protecting downstream circuitry in a DC bus or power rail where the prospective short-circuit current is known to stay below that threshold. The 0.11 melting I²t figure governs how the fuse responds to inrush and surge events. A lower I²t means faster opening under high overcurrent — this part clears quickly on a hard short, but a capacitive input load drawing a brief inrush above 1 A may cause nuisance opening if the energy integral exceeds 0.11 A²s. ## Obsolete — sourcing through independent channels For a BOM line that requires this exact fuse — same 1206 footprint, same 1 A / 63 V DC rating, same SFP series characteristics — the only sourcing path is through independent surplus or broker inventory. ## Board-fit and package specifics The surface-mount termination pads match the common 1206 solder-land pattern used across the industry for resistors, capacitors, and fuses — no custom footprint required. Supplied in Tape & Reel (TR) or Cut Tape (CT) for pick-and-place assembly.","metaTitle":"Littelfuse 1206SFP100F/63-2 SFP Fuse, 1A 63V DC","metaDescription":"Littelfuse 1206SFP100F/63-2 SFP series board mount fuse, 1A, 63V DC, 50A breaking capacity.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Color":"-","Series":"SFP","Package":"Tape & Reel (TR) Cut Tape (CT)","Fuse Type":"Board Mount (Cartridge Style Excluded)","Melting I²t":"0.11","Mounting Type":"Surface Mount","Response Time":"-","Package / Case":"1206 (3216 Metric)","Product Status":"Obsolete","Approval Agency":"-","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.063\\\" W x 0.038\\\" H (3.20mm x 1.60mm x 0.97mm)","DC Cold Resistance":"0.34 Ohms","Voltage Rating - DC":"63 V","Current Rating (Amps)":"1 A","Operating Temperature":"-55°C ~ 125°C","Breaking Capacity @ Rated Voltage":"50A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8939cf38a5e3035b0d6c6bedcc1d525b.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1206SFP100F-63-2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1206SFP100F-63-2 when reusing this data.
