1 A fast-blow protection in a 0603 footprint
The Littelfuse 0467001.NR is a Series 467 surface-mount fuse rated at 1 A with a fast-blow response time, designed for overcurrent protection in compact electronic assemblies. Its 0603 (1608 metric) package and surface-mount mounting suit high-density PCB layouts where space is at a premium, and the tape-and-reel packaging supports automated pick-and-place assembly.
Breaking capacity and voltage ratings
Rated for 32 V AC and 32 V DC, the fuse clears faults up to 50 A at rated voltage — a 50 A breaking capacity that safely interrupts high-energy shorts without casing rupture or arc propagation. The melting I²t of 0.0212 lets you coordinate the fuse with upstream circuit breakers or downstream components; it defines the let-through energy the fuse passes before opening. DC cold resistance of 0.07 Ohms means a 1 A load drops 70 mV across the fuse — negligible in most low-voltage circuits but worth checking if the rail has tight regulation.
Operating range and safety approvals
The fuse operates from -55°C to 90°C, covering industrial temperature environments without derating at the upper end. CSA and UL approvals certify the fuse meets North American safety standards for overcurrent protection, which simplifies regulatory acceptance in equipment sold into those markets.
