UVK2G4R7MPD1TD Capacitors

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are essential components in countless electrical and electronic applications. It is an electric energy storage device that uses electrolysis to increase the capacity of the capacitor. Aluminum electrolytic capacitors are generally divided into two sub-categories, the Polarized Aluminum Electrolytic Capacitors, and the Non-Polarized Aluminum Electrolytic Capacitors. The UVK2G4R7MPD1TD is a type of polarized aluminum electrolytic capacitor.

Polarized aluminum electrolytic capacitors consist of two metal foils and a layer of electrolyte between them. The two foils, termed the anode and the cathode, form an electrical circuit via the electrolyte, which serves as the dielectric between them. The anode foil is usually composed of aluminum coated with an oxide layer, while the cathode foil is composed of a porous material. The foils are generally rolled up together and multiple layers of the capacitor are connected in series to increase the capacity of the capacitor.

The working principle of a polarized aluminum electrolytic capacitor is based on the fact that the capacitance of a capacitor is determined by the surface area, distance between the two foils, and the dielectric material between them. The capacitance is increased by increasing the surface area and the distance between the foils, or by using a material that possesses a larger dielectric constant (like the aluminum oxide).

Polarized aluminum electrolytic capacitors are used in applications that require the higher capacitance and excellent stability, such as power supplies, audio amplifiers, and filters. These capacitors are also often used as power supplies, in power measurement and in high-frequency applications. Furthermore, they offer good thermal stability, high breakdown voltage and high insulation resistance, compared to other types of capacitors.

In summary, the UVK2G4R7MPD1TD is a type of polarized aluminum electrolytic capacitor and it works based on the same principles discussed above. It is capable of providing very high capacitance values and excellent stability for various electrical and electronic applications.
