Methods of solving film capacitors noise

Film capacitors are mainly used in Electronics, House appliance, Communications, Electrified railway, Hybrid electrical vehicle, Wind power generation, Solar electrical energy generation and other industries. Because of the stable development of these industries, the growth of the film capacitor market has been promoted. In the application, it was found that the film was noisy when it was working. Does this noise affect the lifetime? How to solve the noise problem?

The root cause of the noise: The noise of film capacitors appears in some specific work situations. Such as cross-line, buck and other film capacitors. Because of the gap between the films, vibration occurs due to the alternating electric field. So, the noise of the film capacitor has no effect on the quality of use and lifetime.

Methods of solving film capacitors noise:

1.Check that the physical characteristics of all electronic devices are complete.

2.Each circuit has an area function when dividing the area, and it is not necessary to check every circuit to avoid expanding the problem.

3.When measuring, select different instruments according to different functions.

The above three points, strong electricity and weak electricity are applicable. Purchasing film capacitors requires finding quality manufacturers to ensure that their capacitors are not problematic, and pre-sales and after-sales services are guaranteed.
