It clears overcurrents quickly — the fast-blow response time means it opens before downstream silicon can absorb a sustained fault, which matters for protecting sensitive ICs on a densely populated board. Rated for 32 VAC and 65 VDC, with a breaking capacity of 35 A at the AC voltage and 13 A at the DC voltage. That DC rating is the one to watch: on a 48 V telecom rail or a 24 V industrial bus, the fuse can interrupt a short-circuit current up to 13 A without rupturing the package. ## What the ratings mean for your board The melting I²t of 0.0766 A²s tells you how much energy the fuse absorbs before opening — useful for sizing the fuse to ride through inrush without nuisance blowing. A DC cold resistance of 0.0385 Ohms means the voltage drop at rated current is under 60 mV, so it won't steal headroom from a low-voltage rail. Operating temperature spans -55°C to 90°C, which covers most indoor and outdoor equipment enclosures. The 0603 package keeps the footprint small — 1.60 mm x 0.81 mm — so it fits on tight PCB layouts where a larger 1206 or 2410 fuse would crowd the routing.","metaTitle":"046701.5NR Littelfuse 467 Fast-Blow SMD Fuse, 1.5 A","metaDescription":"Active Littelfuse 046701.5NR 1.5 A fast-blow surface-mount fuse, 0603 package, 32 VAC / 65 VDC, CSA/UL approved.
