Need super capacitor voltage advice

[dante_clericuzzio]

I am trying to buy a super capacitor for some experiment but i found that their voltage rating is only up to 16 volt and most commonly 2.7 volt to 5.5 volt...why is the super capacitor with so much capacitance but the voltage is very low? Can it withstand voltage like 20 volt to charge them? ...

I am quite intrigued because of such higher capacitance but very low voltage rating...what is the reason behind that?

Basically, a capacitor is two conductors separated by an insulator. The shorter the distance of separation, the more capacitance you get, but the lower voltage it can stand without breaking down the insulation.

That's sound a logical fact...thanks Bob
