A tantalum capacitor is a type of electrolytic capacitor, a component of electronic circuits. It typically consists of a pellet of tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by conductive material as a cathode. The conductive material serves as the electrodes of the capacitor, while the tantalum pellet acts as a collection plate. The combination of a dielectric oxide layer and the conductive material, results in a capacitor that can store and transport very large amounts of electrical energy.

T491D226K020AT7650, is a tantalum capacitor that is widely used in modern electronics and microelectronics, designed specifically for applications such as switching power and digital displays. This capacitor is a surface mounted package with a capacitance value of 22uF and a maximum operating temperature range of -55°C to +105°C. It is capable of withstanding up to 12V DC and has an operating temperature of +85°C with maximum ripple current of 150mA when used as minimum.

The working principle of the T491D226K020AT7650 capacitor is based on the exchange of charges with the application of an electric field. This phenomenon is known as the capacitor effect and is characterized by the formation of electric double layers in the electrode/electrolyte interface.

When two electrodes are placed in contact with each other, electrons from the anode are attracted to the cathode and form an electric double layer. When an external electric field is applied, these charges migrate towards the anode and cathode side of the device. This charge exchange process results in the formation of electrical dipoles, and thus a capacitance is generated.
