865080463017 Datasheet/PDFAluminum Electrolytic Capacitors are capacitors with an electrolyte that uses the polarization of electric double layers formed by two aluminum electrodes. The 865080463017 application field and working principle of aluminum electrolytic capacitors is quite wide, finding use in power supplies, audio equipment, signal processing, telecommunications, measuring circuits and other electronic functions.
The main advantages of aluminum electrolytic capacitors lie in their high capacitance and low leakage current. The capacitance of aluminum electrolytic capacitors is much larger than that of ceramic capacitors. This is thanks to the fact that due to the existence of the electric double layer structure and aluminum oxide layer, the aluminum electrode has a much higher surface area, which enhances the capacitance. Furthermore, aluminum electrolytic capacitors have a very low leakage current, that is, the leakage current does not exceed the specified operating temperature. This is because the strong binding between the aluminum atoms and the ions in the electrolyte solvents creates a very tight seal, effectively preventing the passage of electrons to the opposite electrode. As a result, the life of the capacitor is extended and the reliability is also improved.
The working principle of an aluminum electrolytic capacitor is quite simple. When the electric voltage is applied to the aluminum electrolytic capacitor, the polarization phenomenon in the electric double layer is used to store charges and generate a charge inside the capacitor. The positive electrode of the capacitor stores positive charges, while the negative electrode stores negative charges. This accumulation of charges creates an electric field between the two electrodes that increases the capacitance of the capacitor. When the voltage is removed, the electric field and the accumulated charges are also removed, allowing for the release of the electric flux.
In addition to the above characteristics, aluminum electrolytic capacitors have other advantages. For example, aluminum electrolytic capacitors have good temperature characteristics, that is, they remain stable even in high temperature environments. Furthermore, they are also resistant to mechanical shock and vibration, making them suitable for use in a variety of electronic devices.
In summary, aluminum electrolytic capacitors are widely used in many electronic applications thanks to their high capacitance, low leakage current, good temperature characteristics, and resistance to mechanical shock and vibration. As such, they are a very important component in many electronic circuits.
