This article is about the reasons why film capacitors produce noise. Recently, I saw some netizens saying that the film capacitors they purchased produced noise during use. I will answer this question in this article. Let's read on!

Film capacitors may produce noise in some specific working situations, such as cross-line, step-down and other ac situations. This is because there is a gap between the films, which causes vibrations under the action of the alternating electric field.Judging from current technology and statistical data, the presence of noise in film capacitors has no significant impact on the performance of the capacitor.This is generally caused by manufacturing process reasons, and technological advances will obviously improve or solve this problem.

Therefore, when purchasing film capacitors, we should look for some experienced manufacturing factories, in order to ensure the quality of our products and after-sales service. We can do some homework before purchasing to avoid unnecessary trouble.
