Re: Surface mount resistors
Pretty much all SMD resistors will be capable of operating at 5VDC. Generally, you're looking at 50V operating voltage. However, the power rating is much more important. I've seen heaps of resistors burn out, not because the voltage was too high, but because it was trying to dissipate too much power. (P = V*I).
In general, power ratings are: 0402(1/16W), 0603(1/10W), 0805(1/8W), 1206(1/4W), 1210(1/3W), 2010(3/4W), 2512(1W), 3616(2W), 4022(3W)
