672D477F025ET4J Working Principle

The working principle of an aluminum electrolytic capacitor is quite simple. In an aluminum electrolytic capacitor, one of the capacitor\'s terminals is connected to a piece of aluminum foil. This aluminum foil is then immersed in an electrolyte solution containing positive ions. The electric field created by the voltage across the two electrodes causes the positive ions to move towards the negative electrode. As the ions accumulate on the negative electrode, an electric capacity is created. The larger the voltage across the capacitor, the more ions will accumulate, thus creating a larger capacity. This charge is what allows the capacitor to store electrical energy.

Additionally, the electrolyte solution itself serves as the dielectric for the capacitor. As ions move across the membrane of the capacitor, they cause a dielectric polarization, which further increases the capacitor\'s capacity. The dielectric polarization also allows the capacitor to operate without degrading performance over time.

Overall, the 672D477F025ET4J aluminum electrolytic capacitor is an ideal solution for a variety of applications due to its robust design, wide range of voltage and temperature ratings, and low equivalent series resistance.
