Super Farad capacitor output current

How do you charge a super capacitor?

Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.

What is a super capacitor used for?

Super capacitors are widely used as a backup power source for realtime clock circuits and memory in microcontroller applications for years. More information in Wikipedia here. This calculator determines timekeeping operation using a supercapacitor based upon starting and ending capacitor voltages, discharge current, and capacitor size.

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 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).

What happens if you charge a super capacitor at a high current?

This information can be hard to find. As well, most methods of balancing will limit the charge and discharge limits of your super capacitor. Meaning that you will possibly negate the function of the balancing circuit, or damage your balancing circuit if you charge at a high current, or discharge at a high current.

Can a super capacitor be discharged down 0 V?
