7 A fast-blow — what the ratings mean for fit
The 1206SFF700F/24-2: Rated 7 A continuous at 24 VDC with a 45 A breaking capacity — this fuse clears sustained overcurrents up to 45 A without rupturing, which covers most low-voltage DC rail faults in board-level power distribution. Fast-blow response and a melting I²t of 1.75 mean it opens quickly on short-circuit but may nuisance-blow on high inrush pulses — a slow-blow sibling in the same package is the better call for capacitive or motor-start loads.
1206 SMD — board-fit and field swap
DC cold resistance of 0.011 Ohms means the voltage drop at 7 A is under 80 mV — negligible in a 24 V rail, but worth checking if the load is sensitive to supply droop.
