Working Principle

T491B225K035AT4860 works by storing energy in electrostatic form between two metallic plates that are covered by an electrolyte. The anode is made from manganese dioxide and the cathode from a metallic oxide, or tantalum pentoxide. The capacitor is polarized with positive voltage to the anode and negative voltage to the cathode, allowing charge carriers to move between the plates. The capacitor\'s capacitance is determined by the relative size of the plates and the spacing between them, which is maintained by a dielectric. When the capacitor is charged, it is able to store the charge and release it when needed. This process is repeated, allowing for higher current to be stored and released in a controlled manner.
