I'm looking to possibly use ATC type fuses instead of shunt resistors for a project. I found this http://www.littelfuse.com/~/media/a...cle/blade-fuses/littelfuse_atof_datasheet.pdf which gave me the idea in the first place. In the chart on the right it gives typical values for voltage drop across the fuse. Are the voltage drop values what to expect at the fuse's rated current? If so is there any sort of curve to consider or will it be a simple ratio to convert the measured drop into a current value? Say with 5A through a 10A fuse would I expect to measure around a .055V drop or is there a curve to work out? Since the values are listed as typical I'm assuming there's a little wiggle room which I can handle a small amount of. The more accurate it is the coolness factor goes up, but as long as I can be within 1 amp after calculations it will be good enough.
