Working Principle of the T491B156K010ZT7280

The T491B156K010ZT7280 is a type of tantalum capacitor, which uses a dielectric tantalum oxide as its material. The component is constructed with two plates (electrodes) separated by a insulating material (dielectric). When an electric field is applied, the dielectric material stores electric charge and creates a capacitance. The amount of charge the capacitor can store (capacitance) depends on the area of the plate, the distance between the plates, and the dielectric material.

When a voltage is applied, current will flow through the component and charge the capacitor. The capacitor will then continue to hold charge until it is discharged. The dielectric material in the component has a low leakage current, meaning it can be used in low power applications. The component also has excellent temperature stability and high ripple current capabilities, making it an ideal choice for a wide range of applications.
