Aluminum Electrolytic Capacitors are widely used in consumer electronics, communications, telecommunication, and automotive industries, due to their large capacitance, high temperature performance and long life. The ULD2E8R2MPD is a type of aluminum electrolytic capacitor used in these industries, especially in power supply and neutralization systems. This section will discuss the application field and working principle of ULD2E8R2MPD.

Application Field

The ULD2E8R2MPD aluminum electrolytic capacitor is most commonly used for power supply and neutralization purposes. The capacitor has a rated voltage of 400V, and a MΩ impedance of 0.045Ω. It is suitable for applications including AC/DC, AC motors, power rectification, DC/DC converters, and railway signal equipment. The ULD2E8R2MPD has excellent power support characteristics and provides extremely strong filtering performance. The capacitor is also suitable for long life applications exceeding 1000 hours.

Working Principle

The working principle of the ULD2E8R2MPD aluminum electrolytic capacitor revolves around electrolyte interaction with the terminal plates. The aluminum plates are used as electrodes, which are bathed in a liquid salt electrolyte. When current is supplied, the electrolyte electrons and plates interact and form a junction. This process is known as double-layer capacitance, and it is what provides the ULD2E8R2MPD capacitor with high capacitance, voltage, and temperature performance.

The electrolyte is composed of a positively charged ionic liquid, polarized within both electrodes. When a potential is applied to the capacitor, the electrolyte ions move to the negative electrode, leaving the positive electrode vacant. This forms a space charge between the two electrodes, and it is this charge that adds to the capacitor’s capacitance. The electrolyte is specially formulated to ensure the capacitor has a long operational life and is free from corrosion and leakage.

Conclusion

The ULD2E8R2MPD aluminum electrolytic capacitor is a specially formulated capacitor that is designed for use in the electronics, communications, and automotive industries. It has a rated voltage of 400V, and features excellent power support characteristics and strong filtering performance. The key to its performance lies in its electrolyte interaction with the terminal plates, which form a double-layer capacitance that provides high capacitance, voltage, and temperature performance. It is suitable for applications including AC/DC, AC motors, power rectification, DC/DC converters, and railway signal equipment, and is particularly suited for long life applications.
