Main Question or Discussion Point

Can anyone tell me the difference in capacitors. Such as the quality control in producing it, the testings, the specs (low esr), brand names, and if its worth buying a 30 dollars 1.5 farad capacitor v.s. a 170 dollars 1 farad capacitor.

thanks

thanks for the information, and averagesupernova, i'm not into car audio. I know that majority of the people who purchase cap's are into car audio, but i'm doing a design project that need a cap to have an actuation time of less than 1 sec.

Well, if you need the capacitor to have a discharging/charging rate of 1 sec, you need to evaluate:

Time Constant = R*C = Time to reach 63% of final value

Hmmmm. Actuation time meaning what? More info please. Depending on what you are doing, the ESR and other things might not mean a darn thing.
