I am attempting to limit the current to a circuit card to 2A. I initially intended to use a fast acting 2A fuse, but none that I am finding are very quick; it will take anywhere from 30s-1hr to blow @2A. It will blow much faster at 4A, but I do not want to allow 4A into my circuit card.
What is the best way to limit the input of the circuit card to 2A? Do I get a 1A fuse that blows quickly at 2A and just hope that it won't be over 1A for an extended period of time? Do I got with a current limiting circuit?
