Types and symbols of capacitors

There are many types of capacitors. In order to distinguish them, several Latin letters are often used to represent the types of capacitors, as shown in Figure 1. The first letter C represents capacitance, the second letter represents the dielectric material, and the third letter and beyond represent the shape, structure, etc.

The picture above is a small paper dielectric capacitor, and the picture below is a vertical square sealed paper dielectric capacitor. Table 1 lists the types and symbols of capacitors. Table 2 shows several characteristics of commonly used capacitors.
