SFS series, Board Mount SMT Fuse, 1206 (3216 Metric), 8 A, 24 VDC, Slow Blow, 60 A Breaking Capacity, UL Recognized.","salesMarkdown":"## Obsolete — sourcing reality for the 8 A slow-blow SMT fuse The 1206SFS800F/24-2: Any replacement requires a parametric match: 8 A current rating at 24 VDC, slow-blow response time, and a 1206 SMT footprint. The 60 A breaking capacity at rated voltage is the interrupt rating — confirm the prospective fault current in your circuit stays below this. ## 8 A, 24 VDC, 60 A breaking capacity — what these ratings mean for fit Rated 8 A continuous at 24 VDC — this is the nominal current the fuse carries without opening under normal conditions. The slow-blow characteristic with a melting I²t of 16.9 means it tolerates short-duration inrush pulses (capacitor charging, motor start, hot-swap) without nuisance opening, unlike a fast-acting fuse of the same current rating. The 60 A breaking capacity at 24 VDC is the maximum fault current the fuse can safely interrupt. If your circuit's prospective short-circuit current exceeds 60 A at 24 VDC, this fuse is not adequate — the arc may not extinguish cleanly. The 0.009 Ohm DC cold resistance is low enough that voltage drop at 8 A is under 75 mV, negligible for most low-voltage DC rails. The fuse's current-carrying capacity derates at elevated ambient; above 85°C the 8 A rating should be reduced per the manufacturer's derating curve (not reproduced here). UL recognition confirms the fuse meets UL 248-14 for supplemental overcurrent protection. ## 1206 SMT package — board-fit checklist Surface-mount placement with tape-and-reel packaging — the reel quantity is set by the manufacturer's standard pack, typically 3000 or 5000 pieces per reel for 1206 fuses. Confirm the reel count with your order quantity. The 1206 footprint is a mature, widely supported SMT package — no tombstoning risk with standard reflow profiles. The 0.97 mm seated height is within the typical clearance envelope for a 1.6 mm PCB with bottom-side components. No special baking or moisture handling is required beyond standard MSL 1 practices for ceramic-body fuses.","metaTitle":"Littelfuse 1206SFS800F/24-2 SMT Fuse, 8 A, 24 VDC, Slow Blow","metaDescription":"Littelfuse 1206SFS800F/24-2 SFS series SMT fuse, 8 A, 24 VDC, 60 A breaking capacity, slow-blow.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Color":"-","Series":"SFS","Package":"Tape & Reel (TR) Cut Tape (CT)","Fuse Type":"Board Mount (Cartridge Style Excluded)","Melting I²t":"16.9","Mounting Type":"Surface Mount","Response Time":"Slow Blow","Package / Case":"1206 (3216 Metric)","Product Status":"Obsolete","Approval Agency":"UL","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":"0.009 Ohms","Voltage Rating - DC":"24 V","Current Rating (Amps)":"8 A","Operating Temperature":"-55°C ~ 125°C","Breaking Capacity @ Rated Voltage":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8939cf38a5e3035b0d6c6bedcc1d525b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the key electrical ratings for 1206SFS800F/24-2?","answer":"8 A continuous current at 24 VDC, slow-blow response with 16.9 melting I²t, and 60 A breaking capacity at rated voltage.
