Trying to learn how to use filter caps (which I believe as called decoupling caps as well) on PCB's to keep things running smoothly, and I expect this is a broad subject, so was wondering if anyone has any useful web links that could teach me a bit about it. More specifically, I'm curious about when to use what types of capacitors, how to size these, and placement preferences. Or perhaps just add some info on this list.
