500 mA fast-blow in a 0603 footprint
The Littelfuse 0467.500NRHF is a 500 mA fast-blow surface-mount fuse in the 467 series, housed in a 0603 (1608 metric) package. It is rated for 32 VAC and 32 VDC with a breaking capacity of 50 A at rated voltage. The fast-blow response means it opens quickly on moderate overcurrents — the 0.0087 melting I²t tells you the energy to clear is low, which limits the fault let-through into downstream silicon.
Breaking capacity and cold resistance
The 50 A breaking capacity at 32 VDC covers most low-voltage rail faults in telecom, instrumentation, and battery-backed circuits. Operating temperature spans -55°C to 90°C, which covers industrial ambient conditions but not extended high-temp exposure above 90°C — derate the current if the board hotspot exceeds that.
Active lifecycle and approvals
Supplied in Tape & Reel (TR) or Cut Tape (CT) — the 0603 package is pick-and-place ready for high-volume assembly.
