i know capacitors are measures en Farads (more often microfarads, mF).. but there is another thing you can see in capactiros, and thats the voltage it can handle.. ie. 220mF 25V ........ my question is, is the voltage thing really important? since the 25v is the max. voltage it can handle, if i am using a 3v power supply, it is the same if i use a 10,16,25,50,63,100v capacitor, right? am i right? or is the voltage thing something different than the max. voltage it can handle?
