EEU-FC1E390B

Aluminum electrolytic capacitors are widely used in consumer electronics and industrial applications. The EEU-FC1E390B is one of the most popular aluminum electrolytic capacitors, thanks to its durability and performance. In this article, we will discuss the application field and working principle of the EEU-FC1E390B.

The EEU-FC1E390B is a polarized, long-life aluminum electrolytic capacitor. It is designed for applications that require stable performance over a wide temperature range and long life. The capacitor is available in three standard case sizes and is typically rated for operation at between -40°C and +105°C. The EEU-FC1E390B has a dielectric of aluminum oxide, with an oxide layer thickness of 15 nm. The capacitor is suitable for use in industrial applications such as computers, cellular phones and other consumer electronics.

Like other aluminum electrolytic capacitors, the EEU-FC1E390B operates according to the principle of electrolytic faraday ionization. The capacitor is constructed from aluminum foil, which is saturated with an electrolyte. When a voltage is applied, the electrolyte ions react with the aluminum foil, causing an accumulation of ions on the surface of the foil. The buildup of ions creates an electric double layer, which acts as an insulator between the two surfaces. This double layer has a capacitive effect, resulting in a charge storage device.

The EEU-FC1E390B capacitor can be used in a variety of applications. In power supplies, it can provide voltage stabilization by smoothing out fluctuations in the input voltage. It can also be used to provide decoupling for noisy signals, reduce electrical noise, and protect against overvoltages or shorts. In telecommunications equipment, it is used to reduce the number of components and to improve signal response time. In automotive and transportation applications, the capacitor is often used to reduce RFI and EMI interference. In addition, it can be used as a filter to reduce AC ripple, or as a buffer to prevent power surges.

The EEU-FC1E390B has several advantages over other aluminum electrolytic capacitors. First, it has a longer life than most other types of capacitors, due to its thicker oxide layer and its ability to withstand higher temperatures. Second, it is generally more reliable than other aluminum electrolytic capacitors, making it a good choice for use in critical applications. Third, its low ESR (equivalent series resistance) makes it suitable for a variety of high-frequency applications. Finally, the capacitor has a comparatively low maximum capacitance rating, making it more suitable for small size and low power applications.

In conclusion, the EEU-FC1E390B is a popular choice of aluminum electrolytic capacitor that is used in various consumer electronics and industrial applications. Its main advantages are its long life, high reliability, low ESR and low maximum capacitance rating. It is a reliable component that can be used in a variety of applications, such as power supplies, telecommunications equipment, automotive and transportation applications, and filters or buffers to reduce noise and power surges.
