If the available short-circuit current in your circuit exceeds 35 A, this fuse is not the right fit; you need a higher interrupting rating. Melting I²t is 0.841 — that number tells you the energy needed to melt the fuse element. It matters for coordination: if you have a downstream component with a known I²t withstand, this fuse should open before that component fails. The 0.00118 Ohms DC cold resistance means the fuse itself drops under 5 mV at rated current, so voltage drop is negligible in most low-voltage rails. ## 0603 SMD — fits tight boards, needs careful soldering Package is 0603 (1608 metric), surface-mount, with dimensions 0.063\" x 0.032\" x 0.012\" (1.60 mm x 0.81 mm x 0.31 mm). That is a tiny footprint — good for dense layouts, but the small pads mean rework is fiddly without a hot-air station. In a field repair, swapping this on site is possible if you have fine tweezers and a controlled iron; the orientation is not polarity-sensitive, so no risk of a backwards install. Operating temperature range is -55°C to 90°C, which covers most indoor and outdoor equipment but not under-hood automotive ambient. The fuse is CSA and UL approved, so it meets North American safety agency requirements for the listed ratings.","metaTitle":"0467004.NR Littelfuse 467 Series 4 A Fast Blow Fuse, 0603","metaDescription":"0467004.NR Littelfuse 467 series 4 A fast-blow board-mount fuse, 0603 SMD, 32 V, 35 A breaking capacity, CSA/UL approved.
