Supercapacitor
This design gave a capacitor with a capacitance on the order of one farad, significantly higher than electrolytic capacitors of the same dimensions. This basic mechanical design remains the
RS offer an extensive range of high-quality double layer supercapacitors from leading brands including Vishay, KEMET, Panasonic, and of course RS PRO. Supercapacitors are categorised based on the design of the electrodes. Electric double layer capacitors have carbon electrodes with a much higher static capacitance than others.
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.
Electric double layer capacitors can charge and store more energy than standard capacitors. They are used in applications such as handheld devices and are now widely used in hybrid vehicles because of their rapid charging rate. Due to their electric flow, they can be applied as backups to primary batteries to ensure a steady electrical current.
(y) Electrolytic capacitors feature nearly unlimited charge/discharge cycles, high dielectric strength (up to 550 V) and good frequency response as alternating current (AC) reactance in the lower frequency range. Supercapacitors can store 10 to 100 times more energy than electrolytic capacitors, but they do not support AC applications.
