What are the classifications of capacitors?


According to analysis and statistics, capacitors are mainly divided into the following 10 categories:

According to the structure, it is divided into three categories: fixed capacitors, variable capacitors, and fine tuning capacitors.

2. Classification by dielectric: organic dielectric capacitor, inorganic dielectric capacitor, electrolytic capacitor, electrothermal capacitor, air dielectric capacitor, etc.

According to the purpose, there are: high-frequency bypass capacitor, low-frequency bypass capacitor, filter capacitor, tuning capacitor, high-frequency coupling capacitor, low-frequency coupling capacitor, and small capacitor.

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

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

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.

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

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.

The principle of supercapacitors

Electric double layer capacitor is a new type of capacitor based on the interface double layer theory proposed by physicist Helmholtz. It is well known that excess charges with opposite symbols appear on the surface of metal electrodes inserted into electrolyte solutions and on both sides of the liquid surface, resulting in potential differences between phases.


Test methods for fixed capacitors

1. Detection of small capacitors below 10pF: Because the capacity of fixed capacitors below 10pF is too small, using a multimeter to measure can only qualitatively check whether there is leakage, internal short circuit, or breakdown. When measuring, a multimeter R can be selected × At 10k gear, use two probes to arbitrarily connect the two pins of the capacitor, and the resistance value should be always high. If the measured resistance value (pointer swinging to the right) is zero, it indicates that the capacitor is damaged due to leakage or internal breakdown.

Function of capacitor

In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a device that can store electric charges and is also one of the commonly used electronic components.
