Additionally, it can be used in the power supplies of computers and domestic appliances, such as refrigerator and washing machines.

The working principle of a tantalum-polymer capacitor is fairly straightforward. It consists of two conductive plates (the anode and cathode plates) that are separated by an insulating material (the dielectric). The dielectric is usually a polymer, such as polypropylene. When a voltage is applied across the plates, the plate material attracts opposite charges and forms an electric field. This electric field stores energy, which can then be used to supply power to the circuit.
