I know that 1 farad (F) is quite a lot of capacitance. So, 1 F capacitors, like the one below, are big. Why do I see so many capacitors that have such high values (sometimes hundreds of Farads) that are so small? (like this one) I must be missing something very basic and obvious here... |
| agehall:
Correct me if I'm wrong (and I probably am!) but isn't that due to different construction and different constraints. The first one you show is a huge cap for use in 12V systems while the other one is limited to 5.5V. That makes a big difference... |
| ggchab:
The small one may also have a high ESR that limits discharge current and would be totally useless in the case of a car audio system. |
| BravoV:
Also ... some of those car audio bling-bling cap are just fakes, they put much-much lower capacitance capacitor in there and put into bling container to impress. :P |
| MyHeadHz:
hmm. I found this article and now I'm even more confused. Are *all* of the car audio capacitors gimmicks? :o |
