How much capacity does a super capacitor have?

This page is an attempt to demonstrate just how much capacity a super capacitor has. A one farad super capacitor can store one million time more energy at a common voltage, than a 1uf capacitor, one billion times more than a 1nf capacitor, and one trillion times more than a 1pf capacitor.

What is a 470 uF capacitor?

Many capacitors that you'd have seen in audio circuits have capacitances such as 470uf or 680uf (micro farads). Capacitors used in high frequency RF applications can be as small as 1pf (pico farad). The farad is a measure of capacitance (or storage capacity).

Do super capacitors have a high voltage rating?

Cool, huh? However, super capacitors have very small voltage ratings, such as 2.5v, 2.7v and 5.5v (Some common values). This makes things difficult, as in order to make our capacitors capable of charging up to a higher voltage, we need to place them in series, which brings a bunch of other variables into play.

What happens if a capacitor bank is full?

When the capacitor bank is full, it will stop accepting energy. It will NOT hurt the capacitors if you keep a charge on them at all times, as long as you are not charging the super capacitors at a voltage higher than they are rated for, or that the bank is rated for.

Are super capacitors dangerous?

Both capacitors and super capacitors can be dangerous, but in different ways. If you have a 500v capacitor that has a capacitance of 100nf, and you touch your finger to the positive and negative lead, you can get a nasty shock.

What is a supercapacitor?

Supercapacitors can be illustrated similarly to conventional film, ceramic or aluminum electrolytic capacitors. This equivalent circuit is only a simplified or first order model of a supercapacitor. In reality supercapacitors exhibit a non-ideal behavior due to the porous materials used to make the electrodes.
