Here is the datasheet for the original F1001 SMD fuse:
I have to admit, I do not understand the?
fusing time chart? It doesn't make sense to me.?
?
For example, take the 501 curve (left most curve). The 501 is supposed to be rated current?of 0.5 A. But to me the curve implies it will never fuse at that current. At 1 amp it appears to tell me it fuses at 0.03 seconds. And for ours, 322, it looks like it would never open at 3.15 A.
I suppose the above makes sense. The fuses don't open at the rated current, only at some point above that current. How fast depends on how much over.
