The capacitor also has the ability to withstand high temperatures, making it an ideal choice for high temperature environment applications.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the use of electrolyte solution as the dielectric and the forming and dissolution of a thin aluminum oxide layer at the surface of the aluminum foils. When a potential is applied, a thin oxide layer is formed on the surface of an oxidizable foil, thus creating the two electrodes of the capacitor. When the charge is applied to the capacitor, the charges start to conduct and accumulate on the surface of the foil, forming the dielectric layer. As the voltage increases, the oxide layer increases in thickness while the capacitance also increases.

The 381LX271M250K012 aluminum electrolytic capacitor is particularly suitable for high power frequency applications due to its large capacitance and low equivalent series inductance and resistance, enabling high current and voltage applications in a small size.
