Aluminum electrolytic capacitors are a type of electrolytic capacitor that use a loose aluminum oxide film as the dielectric material and an electrolytic solution as the cathode. The loose aluminum oxide film allows for greater capacitance than conventional ceramic dielectric capacitors. These capacitors are used in a variety of applications, from power supplies and industrial electronics to consumer electronics and telecommunications.

UPW1E151MPD aluminum electrolytic capacitors are high capacitance, long life electrolytic capacitors. This series is designed specifically for use in switching power supplies, where they provide long life and high reliability. The UPW1E151MPD has a reverse voltage of 220V and a rated capacitance of 470uF. The capacitors use a copper-clad aluminum anode plate and a formed and sealed aluminum fin sleeve as the casing.

The working principle of aluminum electrolytic capacitors is based on the polarization and depolarization of the metal oxides. The metal oxides used in these capacitors are generally aluminum oxide salts or a mixture of metal oxides such as aluminum, tantalum, and niobium. When a voltage is applied to the capacitor, the metal oxides become polarized due to their polar structure. This polarization results in an electric field between the metal plates that stores energy, allowing the capacitor to act as an energy storage device.

When a voltage is applied to the capacitor, a current flows through the electrolyte to charge the capacitor. This current creates an electric field which polarizes the metal oxide, resulting in an increased capacitance. As the voltage across the capacitor is increased, the current through the capacitor increases, causing the capacitance to increase until it reaches the rated capacitance value for the capacitor. The reverse process occurs when a voltage is removed from the capacitor, resulting in the metal oxide becoming depolarized and the capacitance returning to its original value.

One of the main benefits of using UPW1E151MPD aluminum electrolytic capacitors is their high capacitance and long life. The capacitance of these capacitors is higher than that of regular ceramic dielectric capacitors, which makes them ideal for use in high power applications. The capacitors also have a long operating life, making them ideal for high-power applications that require a high-reliability capacitor with long operating life.

UPW1E151MPD aluminum electrolytic capacitors are widely used in switching power supplies and other high-power applications. Due to their high capacitance and long life, these capacitors are well suited for use in applications where high power is required but reliability and long operating life are also a must. They are also particularly well suited for use in industrial electronics, consumer electronics, and telecommunications applications.
