What kinds of capacitors are commonly used? How are they classified?

The capacitors are mainly divided into the following categories according to their structures, uses, manufacturing materials, performance, etc.:

1. According to the structure, it can be divided into three categories: fixed capacitor, variable capacitor and trimming capacitor.

2. Classification by electrolyte: organic dielectric capacitor, inorganic dielectric capacitor, electrolytic capacitor, electric heating capacitor, air dielectric capacitor, etc.

3. It can be divided into high frequency bypass, low frequency bypass, filtering, tuning, high frequency coupling, low frequency coupling and small capacitors according to the purpose.

4. According to different manufacturing materials, it can be divided into: ceramic dielectric capacitor, polyester capacitor, electrolytic capacitor, tantalum capacitor, and advanced polypropylene capacitor, etc

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

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

7. Filter: aluminum electrolytic capacitor, paper dielectric capacitor, composite paper dielectric capacitor, liquid tantalum capacitor.

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

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

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