The cause of the noise generated by the film capacitor

This article wants to talk to you about the noise caused by the film capacitor. Recently, the editors saw on the Internet that some netizens who purchased the film capacitors will generate noise during use. Edit this article for everyone to answer this question, may wish to look down with the editor!

The noise of the film capacitor may be caused by noise in some specific working places, such as over-current, step-down, etc., because of the gap between the films, which is generated by the vibration of the alternating electric field. Based on current technology and statistics, the noise of the film capacitor has no significant effect on the performance of the capacitor. It is generally caused by manufacturing processes, and advances in the process can significantly improve or solve this problem.

Therefore, when purchasing film capacitors, we must look for some highly qualified manufacturing plants, in order to guarantee the quality of our products and to guarantee after-sales. We can do our homework before purchasing to avoid unnecessary trouble.
