First we learn the basic classification of capacitors.
Capacitors can be divided into three main
categories according to the manufacturing process:
Film Capacitor
Electrolytic Capacitor
Ceramic Capacitor
The Structure of Film Capacitor
Metallized Film Construction
The Internal Structure of the Solid Tantalum Electrolytic Capacitor
Ceramic Capacitor
There is a wide range of capacitors, so it is not easy to make it clear in several simple pictures. For more specific explanation, welcome to this awesome site: Apogeeweb!
