Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used components in electronic equipment. They typically offer a high capacitance combined with a low cost and a large form factor. The UVY2AR22MDD1TD series of aluminum electrolytic capacitors are manufactured by a number of companies and are available in a wide range of shapes and sizes.

Application Field

The UVY2AR22MDD1TD series of aluminum electrolytic capacitors are generally used for generalpurpose applications in both switch mode power supplies and power line filters. In addition, they have been used in automotive and battery charger circuits. Other applications include the backing-up of data and power supplies, power conditioning in audio-video systems, analog filters and converters, and motor start ups.

Working Principles

The UVY2AR22MDD1TD series of aluminum electrolytic capacitors is based on Faraday’s law of electrolytic conduction. This law states that the amount of charge passed through an electrolyte is proportional to the applied electric field. The electrolyte in this case is a solution of aluminum oxide and water that acts to increase the electric field between the two electrodes – one of which is connected to a power source and the other connected to ground. The electric field causes electrons to be moved between the two electrodes, resulting in the formation of a capacitor.

When a voltage is applied to the two electrodes of the UVY2AR22MDD1TD series of aluminum electrolytic capacitors, the dielectric properties of the electrolytic solution cause electrons to migrate from the electrode connected to the negative side of the voltage source to the electrode connected to the positive side. This movement of electrons stores electric energy, which allows the capacitor to hold a charge and to be used as a storage device.

When the voltage applied to the two electrodes of the UVY2AR22MDD1TD series of aluminum electrolytic capacitors reverses, the stored electric energy is released, allowing current to flow through the capacitor in the opposite direction. This process is known as capacitor discharge.

The capacity of the UVY2AR22MDD1TD series of aluminum electrolytic capacitors is determined by the size of the electrodes and the dielectric strength of the electrolytic solution. The larger the electrodes, the greater the capacitance. Similarly, the strength of the electric field applied to the electrodes affects the capacitance of the capacitor.
