I have been trying to figure out what decoupling cap I need for the TLC 5940, Ive read that I should put a 47uf electrolytic cap on them. I've looked over the datasheet, and not found anything that suggest what cap to use, the tutorial doesnt have any decoupling cap, and calculating what cap seems to be some kind of magic that nobody really understands.
I've dug through all my spare/scrap parts, and cant find any 47uf caps, i have many caps in various sizes, but that that size. What about voltage rating, what caps do i need? how do I know what size is right?
Im also curious about ordering parts from the big houses like digikey mouser, ... How long does it take to get parts within the US? does it take weeks, or within a week? I've never ordered anything from any of those places, so any tips would be helpful.
