An aluminum electrolytic capacitor is an electronic component that is used for increasing power and stability to electronic circuits. Its essential functioning principle is highly dependant on the generation of electrical field between two metal plates - one of them being an aluminum foil and the other being aluminum oxide that has been initiated by the application of voltage. Accordingly, an aluminum electrolytic capacitor is constructed from two aluminum foils separated by a paper or plastic based dielectric, soaked in an electrolyte. In addition to improving and stabilizing the electric power supply within an electronic system, this kind of capacitor can be used for filtering, smoothing, timing etc. applications.

Specifically, UVZ2W470MHH is a type of aluminum electrolytic capacitor especially designed for DC blocking, output coupling and pulse applications in low voltage switching power supplies. By virtue of its low equivalent series output capacitance, it can be used in relatively high frequency applications. This kind of capacitor is characterized by its electrolyte and rigid construction, small size, high capacitance and low impedance. It provides excellent electrical characteristics including capacitance tolerance, ripple current and excellent self-healing. Furthermore, this type of capacitor allows relatively long life span and high reliability.

UVZ2W470MHH is mainly used for noise suppression, smoothing, decoupling or buffering signals in critical or power circuits in industrial and automotive electronics including motor drives, air conditioning inverter controllers, LED lighting and electric energy systems. With a high energy rating, it is incredibly useful in high vibrations and peak current suppression applications. Furthermore, it can be found being utilized in medical equipment such as X-ray machines.

The working principle of the UVZ2W470MHH capacitor is based on Faraday’s Law of Electrolytic Action. Voltage is applied to the capacitor and it results to electric current which in turn develops a charge on each of the two aluminum foils. This produces a layer of oxide inside the capacitor, forming two oppositely charged plates. As a result, electric field is produced between the two metal plates. When polarized voltage is applied, the outer aluminum foil works as the anode while the inner layer of oxide which forms a layer between the two metal plates, is considered to be the dielectric layer. Consequently, a strong electric field is created within the capacitor.

In conclusion, the UVZ2W470MHH is an aluminum electrolytic capacitor used in industrial and automotive systems in order to improve the electric power capability and stability of circuits. It is mainly designed for DC blocking, output coupling and pulse applications in low voltage switching power supplies. Moreover, it offers excellent electrical characteristics in terms of capacitance tolerance, ripple current and self-healing ability. Ultimately, its essential working principle is based on Faraday’s Law, through the creation of an electric field between two metal plates.
