Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, commonly known as a liquid capacitor or wet capacitor, is a polarized capacitor with high capacitance and an electrical capacity typically higher than 1 μF (1 millionth of a farad). It has two terminals, a positive and a negative. The positive is made of aluminum and is the anode. The negative is either an oxide film or a foil. It is usually filled with a chemical solution containing solvents, electrolytes and conductive salts.

UVR2C4R7MED Application Field and Working Principle

The UVR2C4R7MED is a high-capacity aluminum electrolytic capacitor with capacitance ranging from 2.2 μF to 47 μF. It is suitable for use in a variety of circuit applications such as high voltage power supplies, motor drives, and other applications where a large amount of energy storage is required.

The working principle of the UVR2C4R7MED is based on the principle of electrolytic capacitors. The positive terminal of the capacitor is an aluminum foil that provides the anode. The negative terminal of the capacitor is an oxide film which is mainly composed of aluminum hydroxide and provides the cathode. When a voltage is applied, an electric field is established through the anode and cathode, causing an electrolyte to be drawn to the anode. This electrolyte allows an electrical potential to be created across the terminals.

The electrolyte involved in the working principle of the UVR2C4R7MED is an organic solvent known as dimethylethylmethoxybenzene (DME), which has a high dielectric constant allowing the capacitor to achieve high capacities. The DME also helps to minimize the electrical leakage current and prolong the life of the capacitor through its protective effect. Furthermore, the use of DME helps to maintain the capacitance of the capacitor at high temperatures.

In addition to DME, the UVR2C4R7MED also contains other components such as manganese dioxide, activated carbon, conductive salts, rubidium sulfate and silica gel. The combination of these materials helps to create a more stable electrolytic system, thus improving the capacitance and reducing the electrical leakage current.

The UVR2C4R7MED aluminum electrolytic capacitor is used in a variety of applications such as high-voltage power supplies, control systems, motor drives, communications and audio equipment. Its high capacitance and long life make it an ideal choice for a wide range of applications.
