Aluminum electrolytic capacitors are widely used in a variety of applications, ranging from consumer electronics to industrial equipment. The EEU-FM1A471 is a tantalum electrolytic capacitor that is used for applications requiring high-reliability performance. In this article, we will discuss the application field and working principle of the EEU-FM1A471.

The EEU-FM1A471 is a surface-mount coin-style tantalum capacitor that has a capacitance range of up to 471µF. It is available in three different case sizes, ranging from 2x2x2mm to 5x3x3mm. This makes it suitable for use in a variety of different applications. It is especially useful in applications that require high-reliability performance, such as automotive, avionics, and medical applications.

The EEU-FM1A471 has an electrode structure that consists of a tantalum electrolyte layer between two aluminum layers. The tantalum electrolyte layer acts as a dielectric material, allowing charge to be stored and discharged. The two aluminum layers serve as the positive and negative electrodes of the capacitor.

The EEU-FM1A471 has a voltage rating of 4.5V, making it suitable for use in low-voltage applications such as microcontrollers and logic circuits. It also has a maximum temperature coefficient of ±15% over the temperature range of -55 to +125°C, which makes it suitable for high-temperature environments. The EEU-FM1A471 also has a high resistance to moisture, which makes it suitable for use in humid environments.

The EEU-FM1A471 also has a low leakage current and a high ripple current rating, which makes it suitable for use in applications that require high-frequency and/or large current pulses. The EEU-FM1A471 is also available in radial and surface-mount packages, making it suitable for use in a variety of different applications.

The working principle of the EEU-FM1A471 is fairly simple. When a voltage is applied to the capacitor, current flows through the electrolyte layer and creates a charge across the two aluminum layers. This charge is stored in the capacitor and can be released when the voltage is removed. The capacitor can then be recharged as soon as the voltage is re-applied.

In summary, the EEU-FM1A471 is a reliable, high-performance aluminum electrolytic capacitor suitable for a wide range of applications. It has a wide voltage rating, a high ripple current rating, and a low leakage current, making it suitable for use in low-voltage, high-temperature, and high-humidity environments. Its simple working principle makes it easy to incorporate into existing circuits and systems.
