Aluminum electrolytic capacitors are the most common capacitors used in electronic circuits today. They are available at relatively low cost, and offer the best performance for a given size. The EEU-FC1C331 series of aluminum electrolytic capacitors, from PANASONIC, are especially produced to meet the requirements of demanding high-temperature and large capacitance applications. In this paper, we will discuss the application field and working principle of EEU-FC1C331 series of aluminum electrolytic capacitors.

Application

EEU-FC1C331 series aluminum electrolytic capacitors have wide range of applications including decoupling, DC filtering, smoothing, and time-delay of voltage. Because of the larger capacity, higher temperature endurance, and lower ESR (Equivalent Series Resistance), they are used in power-oriented circuits, such as super power supplies and inverters. They are also used in audio frequency circuit, such as turntables, headsets, and sound boxes.

Working Principle

The working principle of EEU-FC1C331 series aluminum electrolytic capacitors is based on the fact that current flows between two metal plates with a separation of a dielectric substance between them. The dielectric substance consists of an electrolytic layer of oxide on the surface of the metal plates which is formed by the application of a voltage between the two metal plates. The oxide layer increases in thickness, thereby increasing the capacity of the capacitor.

The EEU-FC1C331 series aluminum electrolytic capacitors are rated for secure operation for up to 105°C ensuring superior performance in high-temperature applications. The capacitors are also rated for high capacitance values up to 1 µF. Furthermore, the capacitors are designed with an extended life span, with a rated lifetime of 10,000 hours, making them ideal for long-term usage.

Conclusion

EEU-FC1C331 series aluminum electrolytic capacitors are designed to meet the requirements of demanding high-temperature and large capacitance applications. The capacitors have wide range of applications, including decoupling, DC filtering, smoothing, and time-delay of voltage. The working principle of EEU-FC1C331 series aluminum electrolytic capacitors is based on the fact that current flows between two metal plates with a separation of a dielectric substance between them.
