Selected Category:Supercapacitors

When connecting supercapacitors in series, insert a voltage balancing circuit in parallel with the supercapacitors to suppress voltage imbalance among them.

precaution

Transient recovery voltage may occur with supercapacitors. When handling, first make sure the capacitor is sufficiently discharged.

precaution

We recommend performing regular inspections when using supercapacitors in industrial equipment for extended periods of time. At the same time, please handle with sufficient care when abnormalities occur.

precaution

The activated carbon in supercapacitors is deposited on aluminum foil and used as electrodes.

materials

The current collector in a supercapacitor conducts the charged electrical charge to the collector terminal.

Tags
materials

The electrolyte in supercapacitors is a conductive liquid which affects properties such as internal resistance and withstand voltage.

Tags
materials

The separator in supercapacitors prevents the anode and cathode from coming into contact and shorting. They also ensure that the electrolyte stays evenly distributed. Nippon Chemi-Con uses electrolytic paper.

materials

The DC-internal resistance (DCIR) of supercapacitors is the measurement value for the internal resistance of the capacitor cell, and the direct current normally used for measurement.

technicalterm

The leakage current (LC) of supercapacitors is the minuscule current that flows when the rated voltage continues to be applied to the capacitor.
