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.
Leakage current is a charge current measured from the pin-to-pin voltage across a charge resistor when the supercapacitor is charged for many hours and while the supercapacitor is on charge. Figure 1 shows measurement circuit of leakage current. When the supercapacitor is charged, there is stable parasitic current.
supercapacitor has a high internal resistance, and a small current is needed to keep the charge on the supercapacitor. Leakage current is a charge current measured from the pin-to-pin voltag across a charge resistor when the supercapacitor is ch rged for many hours and while the supercapacitor is on charge. Figure
When the main charging source is disconnected from the supercapacitor, the supercapacitor starts losing its charge because of its high internal resistance. This is called Self-discharge characteristic. It is a voltage drop in charged capacitor after a period with no load condition.
Contact the factory if you plan to use a higher charge current or higher voltage than specified. Self discharge and leakage current are essentially the same thing measured in different ways, due to the supercapacitor construc-tion there is a high impedance internal current path from the anode to the cathode.
All trademarks are the property of their respective owners. Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current.
