Aluminum electrolytic capacitors use the principle of electrolytic polarization to store electrical energy within a thin aluminum oxide film that serves as a physical dielectric between two plates of aluminum foil. This provides superior levels of capacitance and a very low equivalent series resistance (ESR) for a wide range of applications.

EET-UQ2V391CA is a type of aluminum electrolytic capacitor with a solid aluminum anode and a non-solid electrolyte. The anode is a die-cast metal, with a black oil-filled inside. The outer body is made of aluminum, with a tinned copper lead attached to each end. It has a rated working voltage of 25V DC, a diameter of 11.5mm, and a height of 10.8mm. It has a temperature range between -55°C and +125°C, and a capacitance of 390 μF.

The EET-UQ2V391CA capacitor has a wet-type electrolyte, which means that the electrolyte is a conductive medium, and the oxide film formed on the surface of the anode is the dielectric. This type of capacitor is designed for general-purpose applications, where a high level of capacitance and a low equivalent series resistance (ESR) are needed. The main application fields for this type of capacitor include the power supply, automotive, military, and consumer electronics industries.

The working principle of the EET-UQ2V391CA aluminum electrolytic capacitor is the same as that of any other aluminum electrolytic capacitor. When a voltage is applied to the anode, a current flows into the anode and creates a layer of charge on the surface of the anode. This layer of charge acts as a dielectric, and the capacitor stores energy as a result of the repulsive force that is created between the anode and the cathode. The capacitance of the capacitor is determined by the area of the dielectric layer and the dielectric constant of the medium in which the capacitor is operating. The ESR (Equivalent Series Resistance) is a measure of the resistance of the current within the capacitor.

The EET-UQ2V391CA capacitor is designed to provide superior levels of capacitance and ESR for power supply, automotive, military, and consumer electronics applications. It is well-suited to applications where a large capacitance and a low ESR are needed, such as filtering, charging, and switching. The capacitor is also well-suited for applications in which a high level of capacitance and low impedance are required, such as power supply and motor drive circuits. The EET-UQ2V391CA is also known for its long life and low leakage current, making it an ideal choice for a wide range of applications.
