Aluminum Electrolytic Capacitors: EEU-FC1E471B Application Field and Working Principle

Aluminum electrolytic capacitors are a type of capacitor that uses aluminum as the anode and electrolytic solution as the cathode. It has a series of advantages such as large capacitance in a small package, stable electrical properties and long life span. Because of these advantages, aluminum electrolytic capacitors are widely used in electronic circuits and automotive electronics, especially in couples with high DC voltages and large capacitance values, such as in power management circuits and voltage regulators. The EEU-FC1E471B is one such aluminum electrolytic capacitor, developed by the Japanese firm Nichicon. It boasts a small size of 10.2 mm x 10.2 mm and a small case height of 3.2 mm. Its rated voltage includes 10V, 25V, 35V, 50V, and 100V. Its capacitance values range from 10uF to 1000uF. With these small package, high voltage and large capacitance, the EEU-FC1E471B is ideal for power management, voltage regulation, signal processing, filtering and energy storage in high density applications.The working principle of aluminum electrolytic capacitors is based on the Faraday’s Law of Electrolysis. When a voltage is applied across the capacitor, an electric current passes through the electrolyte between the two electrodes. This creates two layers of charge on the two electrodes, Positively-charged ions on the anode and negatively-charged ions on the cathode. The positive and negative ions attract each other, creating an electric field across the aluminum oxide insulating film between the two electrodes, resulting in a charge storage effect. As a result, the EEU-FC1E471B acts like a switch when there is a voltage change in the circuit. The EEU-FC1E471B also features several other technologies that enhance its performance and reliability. The case of the capacitor is made from lightweight, corrosion-resistant aluminum, with a spiral design for optimal heat dissipation. It also features a self-healing electrolytic solution, that can quickly break down any short-circuiting or sparks caused. Furthermore, it is also RoHS compliant, making it safe for the environment. In conclusion, the EEU-FC1E471B aluminum electrolytic capacitor is a reliable and efficient choice for a wide range of power management, voltage regulation, signal processing, filtering and energy storage applications. This is due to its small size, high voltage, large capacitance and enhanced features.
