I don't quite get what makes this DigiKey part suitable for the role of a
fused resistor. I do see that it has specs for 'fusing behavior' but that
aside, I don't see that this series is marketed / sold as a "fusible
One reason I question it, is the fact that the fusing ratings are only
plotted for like 40X or 50X expected current. Can the circuit under
protection be relied upon to produce those levels of current, even under
Always trying to learn..
