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.

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.

What are the classifications of capacitors?

2023-02-22

According to analysis and statistics, capacitors are mainly divided into the following 10 categories: 1. According to structure, they are 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.
