What are supercapacitors & EDLC?
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.
What is a super capacitor?
For those of you who don't know much about super capacitors, here is a little bit of fun theory: Super capacitors act like any other kind of capacitor, only they can store tremendous amounts of energy. Many capacitors that you'd have seen in audio circuits have capacitances such as 470uf or 680uf (micro farads).
What is the maximum capacitance a supercapacitor can provide?
The maximum capacitance that these capacitors can provide is 1 Farad. If the higher capacitance is required, the capacitors will need to be quite large, which may or may not fit into typical electronic circuits. Enter the supercapacitor.
Are Eaton supercapacitors polarized?
Eaton supercapacitors are designed with symmetrical electrodes, meaning they are similar in composition. When a supercapacitor is first assembled, either electrode can be designated positive or negative. Once the supercapacitor is charged for the first time during the 100% QA testing operation, the electrodes become polarized.
Are supercapacitors a battery?
That is why, despite battery-like construction, supercapacitors are classified as capacitors and not batteries. Compared to batteries, supercapacitors can go through several thousands of charge-discharge cycles. Therefore, they can serve as an excellent source of charge or power backup in battery-operated circuits.
What is a farad in a power supply?
The farad is a measure of capacitance (or storage capacity). They are often used in filtering applications, coupling or decoupling applications, or AC-DC smooting applications (there are some large caps in your standard AC-DC power supply that acts to smooth out the ripple on the line).
