250 mA fast blow in a 0603 footprint
The Littelfuse 0467.250NR is a 250 mA fast blow surface mount fuse in the 0603 (1608 metric) package, part of the Series 467 family. It clears overcurrents quickly with a melting I²t of 0.0014, sized for secondary-side protection on low-current rails — think sensor supply lines, I/O port protection, or DC/DC converter input fusing where the trace width can't handle a larger body.
Breaking capacity and voltage rating
Rated 32 V AC and 32 V DC with a breaking capacity of 50 A at rated voltage. That 50 A interrupt rating covers most low-voltage secondary circuits — a 24 VDC control rail or a 12 V battery-backed bus won't exceed this ceiling in a fault event.
Temperature range and storage
The fast blow characteristic holds across the full range — no derating curve needed down to -55°C, though the DC cold resistance shifts slightly with temperature. Supplied in Tape & Reel (TR) or Cut Tape (CT) for pick-and-place; the reel quantity suits volume builds.
