Aluminum electrolytic capacitors are components whose aluminum oxide acts as the dielectric and whose capacitance is determined by the surface area of the oxide film and the thickness of the oxide film. URS0J471MPD is one type of aluminum electrolytic capacitors, which is a long life, small size, low impedance, and high temperature tolerance.

In terms of application field, URS0J471MPD aluminum electrolytic capacitors are widely used in notebook computers, LCD TVs, computer monitors, digital cameras, digital video cameras and industrial equipment, etc. In terms of working principle, URS0J471MPD aluminum electrolytic capacitors operate in a similar manner to the most common type of capacitors. A capacitor is made up of two conductive plates that are separated by an insulator. When a voltage is applied to the capacitor, electric current flows through the plates, creating an electric field that stores charge. In the case of URS0J471MPD aluminum electrolytic capacitors, this electric field is produced by ions that are released in the oxide film of the capacitor, which forms a dielectric between the two plates.

The cathode plate of the URS0J471MPD Aluminium electrolytic capacitor consists of an aluminum foil with a passivation layer with etched ribs. The anode plate is made of an aluminium foil which has been etched to provide an extended surface area and to improve the capacitance value. Each capacitor is also connected with a solderable wire or eyelet for facilitating mounting and making the connection easier.

The capacitance of a URS0J471MPD aluminum electrolytic capacitor is determined by the thickness of the oxide film, the number of ions adsorbed into this film, and the reaction rate between the ions in the oxide film and the aluminum foil. The capacitance increases as the thickness of the oxide film increases, as well as with a decrease in the reaction rate. The capacitance also increases with a decrease in the concentration of ions in the oxide film. As the temperature of the capacitor increases, the resistance of the aluminum oxide film decreases, increasing the capacitance. On the other hand, the leakage current increases with increasing temperature and reduces the capacitor\'s life.

In summary, URS0J471MPD aluminum electrolytic capacitor is widely used in electronic equipment due to its long life, small size, low impedance, and high temperature tolerance. Its capacitance is determined by the thickness of the oxide film, the number of ions adsorbed into this film, and the reaction rate between the ions in the oxide film and the aluminum foil. Its resistance decreases with increasing temperature, increasing the capacitance; however, the leakage current increases with increasing temperature and reduces the capacitor’s life.
