What is an aluminum electrolytic capacitor? Basic knowledge materials on capacitors are currently being offered.

A structure where a separator soaked in electrolyte is sandwiched between two aluminum foils! An easy-to-understand explanation of a typical capacitor.

Here is an introduction to "Aluminum Electrolytic Capacitors (Al-Ecap)." Al-Ecap has a structure where a separator soaked with electrolyte is sandwiched between two aluminum foils, rolled up into a cylindrical shape. One of the aluminum foils has a highly roughened surface and is covered with an oxide layer that functions as a dielectric.
