According to the analysis of the statistics, capacitor is mainly divided into the following classes:

1. According to the structure: fixed capacitor, variable capacitor and trimmer capacitor.

2. According to the electrolyte: organic dielectric capacitor, inorganic capacitor, electrolytic capacitor, electric capacitor and air dielectric capacitor etc.

3, according to utility: high-frequency bypass, low-frequency bypass, filtering, tuning, high frequency coupling, coupling of low frequency, small capacitors.

4. According to the different manufacturing materials: ceramic dielectric capacitors, polyester capacitors, electrolytic capacitors, tantalum capacitors, and advanced polypropylene capacitors and so on

5. High frequency bypass: ceramic capacitor, mica capacitors, film capacitors, polyester capacitors, glass glaze capacitor.

6. Low frequency bypass: paper capacitor, ceramic capacitors, aluminum electrolytic capacitor, polyester capacitor.

7, filtering: aluminum electrolytic capacitor, tantalum capacitor paper condenser, composite paper condenser, liquid.

8. Tuning: ceramic capacitor, mica capacitor, glass film capacitor, polystyrene capacitor.

9. Low coupling: paper capacitor, ceramic capacitors, aluminum electrolytic capacitor, polyester capacitor, solid tantalum capacitors.

10. Small capacitance: metallized paper capacitor, ceramic capacitors, aluminum electrolytic capacitor, polystyrene capacitor, solid tantalum capacitors, glass glaze capacitor, metallized polyester capacitor, the polypropylene capacitor, mica capacitor.
