Working Principle of T491D686K010ZGAC00

T491D686K010ZGAC00 capacitor works on the principle of dielectric absorption and electrolytic action. It consists of two metal foil electrodes, a dielectric layer usually made of a semi-conductive material or ceramic, and an electrolyte in the form of a liquid or paste. It is the combination of the two electrodes and the dielectric layer that creates the capacitor. When voltage is applied across the two electrodes, an electrical field is produced, the strength of which is determined by the thickness of the dielectric layer.

The electrolyte provides ions which are attracted to the electrodes creating an electrical charge on them. This effect is known as electrochemical reaction. As a result, a capacitance is created and a current will flow between the two electrodes. Thus, the capacitor stores energy as electrical charge and can be discharged when voltage is applied across its terminals. T491D686K010ZGAC00 has low ESR and low impedance, making them suitable for applications that require high currents.
