What are the types of capacitors? How can one determine its parameters from the nameplate?

Polyester capacitors, mica capacitors, film capacitors, tantalum capacitors, aluminum electrolytic capacitors, ceramic capacitors, monolithic capacitors, solid-state capacitors, variable capacitors, surface-mounted capacitors, metallized polyester film capacitors. For capacitors whose volume allows for the printing of parameters, those parameters are usually printed right on them (such as 100uF/250V, as well as temperature and brand information); whereas smaller capacitors (such as surface-mount capacitors) have no space for printing such parameters. Please, fellow users, fill in what is missing.

Classification of capacitors: 1. Based on structure, they are divided into three main categories: fixed capacitors, variable capacitors, and trimmer capacitors. 2. Classified by electrolyte: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, and air dielectric capacitors, etc. 3. Classified by application, they include: high-frequency bypass, low-frequency bypass, filtering, tuning, high-frequency coupling, low-frequency coupling, and small capacitors. 4. Based on the manufacturing materials, they can be classified into ceramic capacitors, polyester capacitors, electrolytic capacitors, tantalum capacitors, as well as advanced polypropylene capacitors, among others. 5. High-frequency bypass capacitors: ceramic capacitors, mica capacitors, glass film capacitors, polyester capacitors, and glass glaze capacitors. 6. Low-frequency bypass: paper capacitors, ceramic capacitors, aluminum electrolytic capacitors, polyester capacitors. 7. Filtering: aluminum electrolytic capacitors, paper dielectric capacitors, composite paper dielectric capacitors, liquid tantalum capacitors. 8. Tuning: ceramic capacitors, mica capacitors, glass film capacitors, polystyrene capacitors. 9. Low coupling: paper capacitors, ceramic capacitors, aluminum electrolytic capacitors, polyester capacitors, solid tantalum capacitors. 10. Small capacitors: metallized paper dielectric capacitors, ceramic capacitors, aluminum electrolytic capacitors, polystyrene capacitors, solid tantalum capacitors, glass enamel capacitors, metallized polyester capacitors, polypropylene capacitors, mica capacitors.
