Aluminum electrolytic capacitors, such as the 380LQ472M080K042, are electrical devices that store energy in the form of an electric field. They are composed of two metal plates separated by a dielectric material, which is typically an aluminum oxide layer. These capacitors have a wide range of uses in many electronic devices, such as power supplies, audio systems, and high-frequency circuits. In this article, we will discuss the application field and working principle of the 380LQ472M080K042.

Application Field

The 380LQ472M080K042 is a non-polarized aluminum electrolytic capacitor. This capacitor is designed for widespread applications in power supplies, audio systems, and high-frequency circuits. Its high-voltage and high-power-handling capabilities make it ideal for applications with high currents and high voltages. It also exhibits excellent temperature stability and high capacitance retention, making it suitable for use in applications that require reliability and performance over extended periods.

This capacitor is also widely used in industrial machinery, lighting systems, automotive electronics, and medical equipment. Its small size and low-profile design make it well-suited for space-constrained applications. Additionally, its long life and low equivalent series resistance (ESR) make it suitable for switch-mode power supplies and other applications that require high ripple and transient current-handling capability.

Working Principle

Aluminum electrolytic capacitors, such as the 380LQ472M080K042, use an electrolytic process to produce a thin layer of aluminum oxide on the surface of the aluminum plates. This layer acts as the dielectric material that stores the electrical energy. When the capacitor is subjected to a voltage, the electric field generated across the layers causes the electrons to move and create a charge on the plates. This electric charge is stored in the capacitor until the voltage is removed.

When a voltage is applied to the capacitor, current will flow until the voltage across the plates is equal to the applied voltage. The current flowing through the capacitor is stored as electric charge. The amount of charge stored depends on the capacitance of the device. The voltage and current rating of the capacitor determine the amount of charge it can hold.

The capacitance of the 380LQ472M080K042 is also influenced by the temperature of the device. At high temperatures, the capacitance of the device decreases because the dielectric material (aluminum oxide layer) breaks down. This effect is known as dielectric breakdown and can cause permanent damage to the capacitor. Therefore, it is important to choose the capacitor with the correct operating temperature range.

Conclusion

The 380LQ472M080K042 is a non-polarized aluminum electrolytic capacitor that is used in a wide variety of applications. Its small size and low-profile design make it a good choice for space-constrained applications. It also exhibits excellent temperature stability and high capacitance retention, making it suitable for use in applications that require reliability and performance over extended periods. The working principle of the device is based on the electric field generated between the two metal plates when a voltage is applied, which allows the capacitor to store electric charge.
