A supercapacitor is a specially designed capacitor which has a very large capacitance. Supercapacitors combine the properties of capacitors and batteries into one device. Supercapacitors have charge and discharge times comparable to those of ordinary capacitors.
Supercapacitors have much higher capacitance values compared to the other capacitors (but lower voltage limits), so they are basically the bridge between the capacitors and the batteries. They can store a lot more energy per unit mass compared to the capacitors.
Most logically we would choose FC0H104ZFTBR24 that has discharge capacitor of 0.1F. But..! There are additional parameters that need to be considered when choosing the right supercapacitor. The voltage drop of the supercapacitor is determined by the DC resistance and the back-up current.
Supercapacitors, also known as ultracapacitors and electric double layer capacitors (EDLC), are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.
There are additional parameters that need to be considered when choosing the right supercapacitor. The voltage drop of the supercapacitor is determined by the DC resistance and the back-up current. The DC resistance values of each part number are given in our datasheets. An approximate voltage drop can be calculated from equation below:
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. Cool, huh? However, super capacitors have very small voltage ratings, such as 2.5v, 2.7v and 5.5v (Some common values).
