What the ratings mean for your BOM line
Rated 2.5 A continuous at 32 VDC with a 50 A interrupting capacity at that voltage — this fuse clears a hard short up to 50 A without rupturing the 0603 ceramic body. The slow-blow characteristic (0.63 I²t) handles inrush from capacitive loads or motor starts without nuisance opening. Operating range is -55°C to 125°C, covering automotive under-hood and industrial enclosure ambient. UL recognition means the fuse is accepted for North American equipment compliance without additional agency testing.
0603 (1608 metric) surface-mount package — standard footprint, no special pad geometry. Supplied on Tape & Reel (Cut Tape option available). The ceramic body is compatible with lead-free reflow profiles up to 260°C peak.
