Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as “aluminum capacitors”, employ a very thin aluminum oxide dielectric layer and are widely used in power supply applications. Particularly for higher capacitance values and higher voltage requirements, the aluminum electrolytic capacitor is a popular choice. A particular capacitor model, the UBX2A331MHL, is an example of how an aluminum electrolytic capacitor can be used in electrical and electronic circuits.

Application Field of UBX2A331MHL

The main application field of the UBX2A331MHL capacitor is in the power electronics industry. This particular series offers a wide range of values of capacitance and voltage, and its operating temperature range goes up to 125°C. This makes them ideal for use in applications such as in filter circuits, power supplies, energy systems, and power conditioning. Additionally, these capacitors are often used in pulsed loads, power circuit decoupling, lightning protection circuits, and heavy load filtering in rectifier circuits.

Working Principle of UBX2A331MHL

The UBX2A331MHL is an aluminum electrolytic capacitor that works by incorporating two aluminum foils, a dielectric material made from aluminum oxide, and a conductive liquid with high ion conductivity - typically a mixture of ethylene glycol and boric acid barium. When a potential is applied to the plates, the dielectric absorbs oxygen, which creates an electric double layer; this creates an electric charge within the capacitor, allowing it to store the charge for a period of time.

The capacitance of an aluminum electrolytic capacitor is determined by the area of the electrodes, the separation distance between the electrodes, and the permittivity of the dielectric material. Additionally, the capacitance of a UBX2A331MHL capacitor is also determined by the temperature of the environment in which it is used, as the dielectric will become thinner or thicker depending on the temperature.

Aluminum electrolytic capacitors also feature a wide range of useful characteristics. These include good temperature stability, high insulation resistance, high ripple current capacity, low structural height, and long product life. As such, they are in high demand for many industries.

Conclusion

The UBX2A331MHL aluminum electrolytic capacitor is a widely used part in the power electronics industry. With a wide range of capacitance and voltage values, along with excellent temperature stability, high insulation resistance, and lots of useful characteristics, the UBX2A331MHL is ideal for various power supply applications.
