Series 467 board-mount fast-blow fuse, 0467.500NR, 0603 (1608 metric) package, 500 mA, 32 VAC/DC, 50 A breaking capacity, 0.187 Ω cold resistance, 0.0087 I²t.","salesMarkdown":"## 500 mA fast-blow in a 0603 footprint The Littelfuse 0467.500NR is a 500 mA fast-blow surface-mount fuse in the 0603 (1608 metric) package, part of the Series 467 board-mount family. It clears in under a cycle on overload — the 0.0087 melting I²t means it will hold through brief inrush pulses that stay below that energy threshold, but opens quickly on a hard fault. ## Breaking capacity and coordination Rated breaking capacity is 50 A at 32 VAC or 32 VDC. That is the maximum fault current the fuse can safely interrupt without rupturing the ceramic body — if the available short-circuit current at the board exceeds 50 A, the fuse may not clear the fault and the board trace or upstream protection must handle the energy. DC cold resistance is 0.187 Ω typical, which at 500 mA produces an I²R voltage drop of about 47 mV and a self-heating power of 23 mW — negligible in most low-voltage circuits, but worth checking if the rail is marginal. ## Approvals and sourcing posture Carries CSA and UL approvals, so it is accepted in North American and Canadian equipment without additional agency review. No pin-compatible second-source alternative is documented in the 467 series — the fuse is a one-to-one BOM position.","metaTitle":"Littelfuse 0467.500NR 467 Series Fast-Blow Fuse, 500 mA","metaDescription":"Littelfuse 0467.500NR, 500 mA fast-blow board-mount fuse in 0603 package. 50 A breaking capacity at 32 VAC/DC.
