Obsolete — sourcing reality for this 6 A fast-blow fuse
Littelfuse has marked the 0603SFF600F/24-2 as obsolete. This part is available through independent surplus and broker channels, not from the factory. The 0603SFF600F/24-2 is a 6 A, 24 VDC fast-blow fuse in the SFF series, with a 35 A breaking capacity at rated voltage. The 1.125 melting I²t means it clears fast on a hard short, but the low DC resistance (0.012 Ohms) keeps voltage drop minimal in the steady state.
