All capacitors have voltage limits. While the electrostatic capacitor can be made to withstand high volts, the supercapacitor is confined to 2.5–2.7V. Voltages of 2.8V and higher are possible, but at a reduce service life. To get higher voltages, several supercapacitors are connected in series.
Unlike ordinary capacitors, supercapacitors do not use a conventional solid dielectric, but rather, they use electrostatic double-layer capacitance and electrochemical pseudocapacitance, both of which contribute to the total energy storage of the capacitor.
High-voltage DC capacitors are designed to handle and store significant amounts of direct current (DC) voltage, making them crucial for applications requiring stable, efficient energy storage and regulation. Our range of high-voltage DC capacitors provides superior performance, with robust construction.
Due to the supercapacitor's discharge current limit, the usable capacity is diminished considerably. Another real-life characteristic afecting the usable capacity of the power source is its internal resistance. Supercapacitors for DC applications refer to this as the ESR, as previously described.
