UVR2A220MEA

Aluminum electrolytic capacitors are an important component in many applications in all areas of electrical engineering. UVR2A220MEA is a radial-leaded aluminum electrolytic capacitor, with long life and low impedance characteristics, also suitable for high temperature applications. The following article aims to explore the UVR2A220MEA application fields and working principle, so as to provide a better understanding of the product.

Application Field of UVR2A220MEA

The UVR2A220MEA belongs to high temperature, long life aluminum electrolytic capacitors. It has two category - low impedance and general purpose, and different parameters enough to meet various needs, mainly used for interference elimination, precision frequency filtering, electric power and motor, etc. Electric and electronic products that often require good temperature stability, such as frequency accuracy, also prefer the UVR2A220MEA.

UVR2A220MEA capacitors have mainly two types of mounting, through-hole and surface-mounting. Its characteristics are: The excellent current derating; The application on high temperature, its rated temperature can reach up to 105°C; The use on high ripple current; The long life, because of these features, it is widely used in consumer electronic devices, office automation, home appliance, and automotive applications.

Working Principle of UVR2A220MEA

Before viewing the working principle of UVR2A220MEA, it is necessary to understand the basics of aluminum electrolytic capacitors. Generally, a electrolytic capacitor consists of two plates made of aluminum foil and a dielectric material, typically a high-grade plastic, wrapped around it. One plate is placed on the inside of the capacitor and the other on the outside. In between the two plates is an electrically conductive material, usually a solvent and an electrolyte, which allow current to flow between them.

The level of capacitance of the UVR2A220MEA is determined by the size of the aluminum plates and the thickness of the dielectric layer. In an aluminum electrolytic capacitor, the anode is formed by the aluminum foil and the cathode by the cylindrical shape of the capacitor itself. The acting force of the capacitor is the voltage across its terminals. This voltage pulls the electrolyte molecules from the electrolyte solution towards the aluminum plates. The constant pull of the voltage causes the molecules to form a layer of film over the surface of the plates. This film is called the dielectric and can store energy when a current is applied between the terminals.

The working of UVR2A220MEA is the same as other electrolytic capacitors. When subjected to an external voltage, the electrolytic Solution forms a layer of dielectric material on the aluminum plates. This layer allows the capacitor to store energy in the form of an electrical charge. After the application of the external voltage, the UVR2A220MEA can deliver a current that is limited only by a resistance and series opposition provided by the internal components. This allows the capacitor to provide a high instantaneous current output.

The two main types of UVR2A220MEA, low impedance and general purpose, differ in their polarities, with the low impedance having a positive and negative terminal, and the general-purpose having only a single terminal. This can be attributed to their differing internal structures, with the low impedance having two separate plates and the general purpose having only one. Low impedance capacitors generally provide a higher capacitance and charge ability than the general purpose.

Conclusion

This article has explored the application fields and working principle of UVR2A220MEA capacitors. UVR2A220MEA capacitors are long-life, high-temperature aluminum electrolytic capacitors which come offered in low-impedance and general purpose forms. These components work by forming a dielectric layer on the aluminum plates which allow the capacitor to store energy in the form of an electrical charge. These features make UVR2A220MEA capacitors ideal for use in various consumer electronic devices, office automation, home appliance, and automotive applications.
