That 3 A continuous rating sets the trip threshold — sustained current above that level heats the element until it opens. The 32 V ceiling matches low-voltage rails common in telecom, industrial control, and consumer electronics. ## Fast-blow response and I²t Fast-blow response means the fuse clears quickly on moderate overcurrents — it does not ride through inrush like a slow-blow would. The melting I²t of 0.2403 tells you the energy needed to open the element; below that threshold the fuse holds, above it the arc extinguishes. For a 3 A rail, this I²t is low enough that a short-circuit fault clears in under a millisecond at typical fault currents. Cold resistance is 0.017 Ohms — at 3 A the voltage drop is about 51 mV and the self-heating is about 0.15 W. That is negligible for most board-level power paths but matters if you are stacking multiple fuses in series or running near the temperature derating curve. ## Breaking capacity and fault current limits Breaking capacity is 35 A at the rated voltage. This is the maximum fault current the fuse can safely interrupt — if your circuit's prospective short-circuit current exceeds 35 A, this fuse may not clear the fault without rupturing. In a typical 32 V rail fed from a small transformer or a limited-current supply, 35 A is often adequate; on a high-capacity battery or a stiff bus, you need a higher interrupting rating. ## 0603 SMD package and board fit The 0603 (1608 metric) package measures 1.60 mm x 0.81 mm x 0.31 mm — a standard footprint that reflow-solders with the same profile as chip resistors and MLCCs. Surface-mount mounting means it sits flat on the PCB, saving vertical space vs a cartridge holder. The Tape & Reel packaging is the production-friendly format for pick-and-place. ## Operating temperature and approvals The operating temperature range is -55 °C to 90 °C, covering outdoor telecom cabinets, industrial enclosures, and automotive cabin environments without derating at the cold end. CSA and UL approval means the fuse is accepted in North American and Canadian regulatory jurisdictions — a check-box for UL 60950 or UL 62368 power supplies.","metaTitle":"0467003.NR Littelfuse 467 Series Fast-Blow SMD Fuse, 3 A","metaDescription":"Littelfuse 0467003.NR 467 series fast-blow SMD fuse, 3 A at 32 V AC/DC, 0603 package.
