It is rated for 32 V on both AC and DC circuits, with a breaking capacity of 35 A at rated voltage — meaning it can safely interrupt a short-circuit fault up to that level without rupturing the package. ## What the ratings mean for the board The 0.0903 melting I²t value tells you the thermal energy needed to open the fuse element — useful for sizing the fuse against inrush current from a capacitive input or a motor start. A cold DC resistance of 0.031 ohms keeps the voltage drop low at rated current, so the fuse does not heat the board unnecessarily in normal operation. The fast-blow response time means this fuse opens quickly on overcurrent, protecting sensitive semiconductor loads like a downstream regulator or a sensor module. The -55°C to 90°C operating range covers most indoor and outdoor equipment environments, though the fuse's current-carrying capacity derates near the upper end of that band. ## Approvals and compliance Supplied on Tape & Reel (TR) or Cut Tape (CT) for pick-and-place assembly. The 0603 footprint is a common industry standard, so no board layout change is needed if this replaces another 0603 fast-blow fuse in the same current rating.","metaTitle":"Littelfuse 04671.75NRHF 467 Series 1.75 A Fast Blow SMD Fuse","metaDescription":"Littelfuse 04671.75NRHF, 1.75 A fast-blow SMD fuse in 0603 package. 35 A breaking capacity at 32 V.
