KnightElite:most ppl commonly use "m" to represent microfarad. I'd like to see a 31000 megafarad("Mf") capacitor...
Grayson:I dont understand what you are trying to say. A 2000 microfarad capacitor is a 2000 microfarad. Now yes it is has a insulation rating. A 1000 volt 2000 mfd will not charge up to 1000 volts with a 12 voltinput if thats what you are thinking. If what you are trying to say is that most rectifiers have a higher voltage output under no load than their input that is true. But it will not be a situation of "better". If the voltage is too high the insulation will be pierced and will destroy the capacitor. Another interesting fact: some capacitors work better around their rated voltage. 2x 25000 microfarad 70 volt capacitors gave me poorer regulation that 2x 24000 40 volt capacitors gave me on my 20 volt psu(drops to about 13 under heavy load).
