Supercapacitor | Capacitor Types | Capacitor Guide
While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts. Supercapacitors are polar devices, meaning they have to be connected to the circuit the right way, just like electrolyte capacitors.
High-voltage capacitor in a low-voltage system
A high voltage capacitor will have it''s capacitance rated at low voltage meaning when operated close to it''s rated voltage the capacitance will be much lower. This is why the different MLCC capacitor dielectric types exist, they guarantee a certain capacitance vs voltage characteristic (amongst other things) $endgroup$ –
