That figure governs the downstream trace and PCB clearance design, not the 2.5 A continuous rating. ## Melting I²t and cold resistance — coordination numbers Melting I²t is 0.2066 A²s — this is the energy needed to open the fuse element. It determines selectivity with upstream breakers or fuses: a downstream fault must clear before the upstream device sees enough energy to trip. For a 2.5 A fast-blow at 32 V, 0.2066 A²s is low enough that a typical 10 A branch breaker stays closed during the fault. DC cold resistance is 0.021 ohms typical. ## Approvals and temperature envelope CSA and UL approved — the fuse is listed for use in North American and Canadian equipment without additional agency testing. Operating temperature range is -55°C to 90°C, covering industrial and automotive interior environments.","metaTitle":"Littelfuse 046702.5NRHF 467 Series Fuse, 2.5 A, 32 V","metaDescription":"Littelfuse 046702.5NRHF 467 Series fast-blow surface-mount fuse, 2.5 A at 32 VAC/DC, 35 A breaking capacity.
