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 makes supercapacitors different from other capacitors?

Available in a wide range of sizes, capacitance and modular configurations, supercapacitors can cost-effectively supplement and extend battery life, or in some cases, replace batteries altogether. What makes’ supercapacitors different from other capacitor types are the electrodes used in these capacitors.

What does L1 & L2 mean in a supercapacitor?

L1= Load life rating of the super capacitor (typically 1000 hours at rated temperature). L2= expected life at operating condition. Tm= Maximum temperature rating of the supercapacitor. Ta= Ambient temperature the supercapacitor is going to be exposed to in the application. Vr = rated voltage of capacitor. Warning.

How do you measure the capacitance of a supercapacitor?

Supercapacitors have such large capacitance values that standard measuring equipment cannot be used to measure the capacity of these capacitors. Capacitance is measured per the following method: Charge capacitor for 30 minutes at rated voltage. Discharge capacitor through a constant current load. Measure voltage drop between V1 to V2.
