Working Principle

An aluminum electrolytic capacitor consists of an anode and a cathode, separated by an electrolyte made of aluminum foil. The anode foil is etched with a pattern of parallel stripes which increases its surface area and helps to maximize the surface. The cathode foil is coated with an electrolyte. The electrolyte is an ionic salt solution which acts as a pseudo-junction between the anode and cathode.

When a voltage is applied between the anode and cathode, current flows through the electrolyte and forms an electric field. This electric field causes an electric polarization which attracts and stores electrical charges on the anode and cathode. This charge accumulation results in the capacitance of the capacitor. When the voltage is removed, the electric charges remain stored in the capacitor for a short period of time, releasing energy gradually.

B43508E2158M000 capacitor also utilizes another type of polarization called tantalum polarization, which help in exploiting the full capacitance of the capacitor. Tantalum polarization works by forming an oxide layer on the surface of the anode, which increases the anode area and thus provides a higher capacitance. The tantalum polarization also helps in improving the operating voltage and temperature range.
