Sorry to ask a question that I feel I should be able to google, but I'm kind of stuck. I have some different 5v AC/DC power supplies that I need to plug into the wall and use to power rgb LEDs. The max currents that I need to draw from these supplies are 2,4A, 1,2A, 0,9A, 0,6A, so I use one power supply 2,5A, one 1,5A (this one is variable 3-12V, I'm assuming that I get minimum 1,2A at 5v) and the rest 1A. What value capacitors do I put across 5v and gnd in these particular circumstances? I get that they should be rated for 10v as a safety, but I don't know how to get to a good number on capacitance. No datasheets available to me on the power supplies, but on the 1A supply it says 300mV ripple on the web site where I buy them. Thanks!
