What the 5 A rating and 35 A breaking capacity mean on the bench
The 0467005.NR is a 5 A fast-blow fuse in the Littelfuse 467 series, housed in a 0603 (1608 metric) surface-mount package. It clears overcurrents up to 35 A at 32 V AC or DC — that breaking capacity tells you it can interrupt a hard short on a 24 V rail without the fuse body rupturing or the arc sustaining.
Melting I²t and cold resistance — sizing for inrush and voltage drop
With a melting I²t of 0.9 A²s, this fuse tolerates brief inrush spikes — like the charging current of a 100 µF cap on a 5 V rail — without nuisance opens. The 0.0089 Ohm cold resistance means at 5 A the voltage drop is under 45 mV, so it won't starve downstream circuitry of headroom.
