Rated for 32 V AC or DC circuits, it is suited for low-voltage power rails, battery management, and general-purpose board-level protection where space is tight. ## Breaking capacity and coordination With a breaking capacity of 35 A at rated voltage, the fuse can safely interrupt fault currents up to that level without rupturing or arcing, which is critical for protecting downstream silicon and PCB traces. The melting I²t of 0.0903 A²s helps coordinate with the let-through energy rating of the load — a low I²t means the fuse opens fast enough to protect sensitive ICs from thermal damage during a short circuit. DC cold resistance of 0.031 ohms at room temperature keeps voltage drop and power dissipation low under normal load, so the fuse does not heat up unnecessarily during continuous operation. ## Board-fit and assembly The surface-mount footprint saves board space compared to through-hole alternatives, making it a good fit for dense PCBs in portable or space-constrained equipment. ## Regulatory and environmental compliance The fuse carries CSA and UL approvals, confirming it meets North American safety standards for overcurrent protection devices. Rated for operation from -55°C to 90°C, it can be deployed in industrial, automotive, and outdoor equipment where ambient temperatures vary widely.","metaTitle":"Littelfuse 04671.75NR 467 Series Fast-Blow Fuse, 1.75 A","metaDescription":"Littelfuse 04671.75NR 467 Series fast-blow surface-mount fuse, 1.75 A, 32 V AC/DC, 35 A breaking capacity, 0603 package.
