Aluminum electrolytic capacitors are components in electrical systems that store electrical energy and protect against power surges, making them an essential component of many electronics. The EEU-FC1E390H is an aluminum electrolytic capacitor designed for specifically optimized for use in automotive applications, such as engine and alternator control, starter motors, and various electronic sensing and control systems.The main components of the EEU-FC1E390H consist of a metalized aluminum electrolyte core and a housing that hosts the oxide and the anode layer which works as the dielectric. The metalized core is made up of an aluminum tube and a electrolyte solution, which when combined together, act as the anode. The electrolyte solution also serves as the cathode and is what allows the capacitor to store the electrical energy. Additionally, the metalized core of the EEU-FC1E390H has a very low resistance value, allowing it to have superior stability and long life.The EEU-FC1E390H is capable of working with a wide range of voltage, from 50V to 150V, though it provides the maximum level of performance at the specified nominal voltage. It is especially useful for applications that require high capacitance density and that also need a low ESR value. The EEU-FC1E390H is designed to provide the highest level of performance with minimal power loss, making it an ideal choice for automotive applications.The EEU-FC1E390H is capable of handling up to 5A of current, and it offers excellent ripple current capabilities, allowing for more reliable operation at higher temperatures.

Furthermore, the EEU-FC1E390H is designed with a Kapton tape layer for additional mechanical protection and heat protection. Finally, the EEU-FC1E390H features a uniform and flat lead configuration for better soldering and packaging.The working principle of the EEU-FC1E390H is based on the electrochemical nature of aluminum electrolytic capacitors. When connected to a power source, the capacitor will draw current, which creates an ionic potential difference between the electrolyte and the anode. This process causes the oxide layer on the electrolyte to become polarized and act as a dielectric, storing the electrical energy in the capacitor. As the current fluctuates, the dielectric layer will release or absorb the charge accordingly.In summary, the EEU-FC1E390H is an aluminum electrolytic capacitor designed for automotive applications, offering a high level of performance with minimal power loss. It is able to handle up to 5A of current and is capable of working with a wide range of voltages, providing excellent ripple current capabilities and durability. The capacitor is also designed with superior heat and mechanical protection, along with Kapton tape layers for additional protection. Finally, its working principle is based on the electrochemical nature of aluminum electrolytic capacitors.
