The 50 A breaking capacity at rated voltage means the fuse can safely interrupt a short-circuit fault up to that current without rupturing or sustaining an arc — adequate for most low-power DC supplies and battery-backed circuits, but not for high-energy mains-fed rails. Melting I²t of 0.0212 A²s is the energy required to open the element; this value governs coordination with downstream semiconductors and lets you verify that the fuse clears before a protected IC's surge rating is exceeded. Housed in a standard 0603 (1608 metric) surface-mount package — 1.60 mm x 0.81 mm x 0.31 mm — the footprint matches the common chip resistor/pad layout for this case size, so no special land pattern is needed. Supplied on tape and reel (cut tape available), compatible with high-speed pick-and-place assembly. ## Approvals and temperature envelope Carries CSA and UL recognition — the two primary marks for North American overcurrent protection — confirming the fuse has passed the required interrupting and endurance tests per UL 248-14. Rated for an operating ambient of -55 °C to 90 °C, which covers most indoor and outdoor equipment enclosures; the 90 °C ceiling is the fuse-body temperature, not the PCB hotspot, so derate if the local ambient near the fuse exceeds that figure.","metaTitle":"Littelfuse 0467001.NRHF 467 Series 1A Fast Blow Fuse, 0603","metaDescription":"Littelfuse 0467001.NRHF 467 series, 1 A fast-blow surface-mount fuse in 0603 package. 32 V AC/DC rating, 50 A breaking capacity.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Color":"-","Series":"467","Package":"Tape & Reel (TR) Cut Tape (CT)","Fuse Type":"Board Mount (Cartridge Style Excluded)","Melting I²t":"0.0212","Mounting Type":"Surface Mount","Response Time":"Fast Blow","Package / Case":"0603 (1608 Metric)","Product Status":"Active","Approval Agency":"CSA, UL","lifecycle_stage":"unknown","Size / Dimension":"0.063\\\" L x 0.032\\\" W x 0.012\\\" H (1.60mm x 0.81mm x 0.31mm)","DC Cold Resistance":"0.07 Ohms","Voltage Rating - AC":"32 V","Voltage Rating - DC":"32 V","Current Rating (Amps)":"1 A","Operating Temperature":"-55°C ~ 90°C","Breaking Capacity @ Rated Voltage":"50A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/649812335218789f332d0f5127374e6a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 0467001.NRHF and how is it quoted?","answer":"No in-stock or lead-time figures are published here."},{"question":"What is the DC cold resistance of 0467001.NRHF?","answer":"The DC cold resistance is 0.07 Ohms.
