Its slow-blow characteristic (melting I²t of 0.18) means it tolerates brief inrush current spikes — capacitor charging at power-up or a motor start — without opening, while still clearing sustained overloads. The 50 A breaking capacity at 32 V DC tells you the fuse can safely interrupt a fault current up to that level without arcing across the element or rupturing the ceramic body. In a 24 V rail with a stiff battery or bulk capacitor bank, that 50 A rating is the margin between a clean open and a cascade failure. ## Obsolete — sourcing reality for a discontinued line Availability is limited to independent surplus and broker inventory. Each lot is confirmed at quote time — no standing stock is held. The UL recognition means the fuse carries the same safety certification as the production-run parts, but date codes will be past the original production window. ## Footprint and environmental envelope The 0603 (1608 metric) case is a standard surface-mount footprint — 1.60 mm x 0.80 mm x 0.80 mm. No special pad geometry is needed beyond the manufacturer's recommended land pattern for 0603 fuses. DC cold resistance is 0.1 Ohm, so at 1.5 A the voltage drop is 150 mV — negligible on a 24 V or 12 V rail, but worth factoring into a 3.3 V supply headroom budget.","metaTitle":"Littelfuse 0603SFS150F/32-2 SFS Fuse, 1.5 A, 32 V DC","metaDescription":"Littelfuse 0603SFS150F/32-2 SFS series, 1.5 A, 32 V DC, slow-blow, 50 A breaking capacity, UL recognized.","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":"0.18","Mounting Type":"Surface Mount","Response Time":"Slow Blow","Package / Case":"0603 (1608 Metric)","Product Status":"Obsolete","Approval Agency":"UL","lifecycle_stage":"unknown","Size / Dimension":"0.063\\\" L x 0.031\\\" W x 0.031\\\" H (1.60mm x 0.80mm x 0.80mm)","DC Cold Resistance":"0.1 Ohms","Voltage Rating - DC":"32 V","Current Rating (Amps)":"1.5 A","Operating Temperature":"-55°C ~ 125°C","Breaking Capacity @ Rated Voltage":"50A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8300","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/0603SFS150F-32-2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/0603SFS150F-32-2 when reusing this data.
