The working principle of aluminum electrolytic capacitors, such as the EKXF401ELL8R2MJ16S, is based on the electrochemical alignment of ions on an electrolyte-soaked aluminum foil. The ions travel between the two aluminum foils, which creates a charge separation. This charge separation creates the capacitance of the device. The capacitance is then measured by the applied voltage and the voltage drop.

The electrodes on the foil act like a microfilter, allowing only the smallest particles of anionic species to move within the structure of the foil. The anionic species are ions such as chloride or fluoride, which flow through the electrolyte. This flow is slowed down by the high surface tension of the electrolyte and the high resistance of the anionic species. This creates an electrochemical cell with a positive and negative pole.

The liquid electrolyte acts as a bridge between the two electrodes, allowing the anionic species to move within the structure of the foil. The movement of ions creates an electric field that further contributes to the capacitance of the device. As the voltage applied between the two aluminum foils increases, more anionic species electrons are attracted to the positive electrode, resulting in a higher capacitance. This is known as the “stray field effect”.

The EKXF401ELL8R2MJ16S is a reliable and robust aluminum electrolytic capacitor that is used for many different applications. It has a wide range of operating temperatures, long rated life, and high reliability. Its wide range of applications shows its versatility and usefulness in power supplies, DC-DC converters, audio equipment, SMPS circuits, and communications equipment. Its working principle is based on the electrochemical alignment of ions on an electrolyte-soaked aluminum foil, which further contributes to its high capacitance and reliability.
