Dingfeng Capacitor--Differences between polar and non-polar capacitors

Differences between polar and non-polar capacitors
Polarity and non-polarity capacitance are the same in principle. They both store and release charges. Voltage on the plate can not change abruptly.

The difference lies in the different media, different performance, different capacity, different structure, resulting in different use environment and uses. Conversely, according to the needs of production practice, people have experimentally manufactured capacitors with various functions to meet the normal operation of various electrical appliances and the operation of new equipment. With the development of science and technology and the discovery of new materials, more high-quality and diversified capacitors will continue to emerge.
Performance is the demand for use, and maximizing demand is the demand for use. If metal oxide film capacitors are used as filters in the power supply of TV sets, the capacitor capacity and voltage withstand required for filtering should be achieved. I'm afraid that only polar capacitors can be used in the chassis, and polar capacitors are irreversible. That is to say, the positive pole must be connected to the high potential terminal, and the negative pole must be connected to the low potential terminal. Generally, the electrolytic capacitor is above 1 microfarad. It can be used for coupling, decoupling, power filter and so on. Most non-polar capacitors are below 1 microfarad.
