The film capacitor has many excellent characteristics, non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Therefore, a thin film capacitor is used in a large amount in an analog circuit. What the editor wants to tell yo

The use of film capacitors in a wet environment makes the surface of the film capacitor gradually condensate. These water will increase the leakage current of the film capacitor, which causes the loss of the capacitor to increase. If the moisture in the surface of the film capacitor or the water in

We all know that any substance is relatively insulated. When the voltage at both ends of the matter increases to a certain extent, the material can be conductive, which we call the breakdown voltage. Capacitors are no exception. Capacitors are not insulators after breakdown. But in secondary school,

With the development of science and technology and the advantages of film capacitors instead of electrolytic capacitors, the frequency of using thin-film capacitors is higher and higher. Today, Xiaobian will share with you the principles of thin film capacitors in AC circuits. In middle school, ther

We can start with the structure of the film capacitor. The simplest capacitance is made of insulating dielectric. After electrification, the polar plate is electrified to form a voltage (potential difference), but the intermediate is not conductive because of the insulating substance. However, this

New energy vehicles refer to the use of unconventional vehicle fuel as a source of power. New energy vehicles include hybrid vehicles, pure electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, other new energy (such as efficient energy storage, dimethyl ether) vehicles and other

Polyester film (terylene) capacitor

Composite film capacitor

Film capacitor manufacturers should pay attention to the selection of capacitors: rated voltage. The so-called rated voltage refers to the voltage applied to the two ends of the capacitor by the film capacitor which can work normally, stably and reliably within a certain period of time in the circui
