Method for solving film capacitance noise

Film capacitors are mainly used in electronics, home appliances, telecommunications, electric power, electrified railways, hybrid vehicles, wind power, solar power generation and other industries. The stable development of these industries has promoted the growth of the film capacitor market. In operation, some users find that the film is noisy when it is working, and this noise will affect the life. How to solve the noise problem?

The root cause of noise: the noise of film capacitors. In some specific work situations, such as crossover, buck, etc., there may be noise in the film capacitors. This is because there is a gap between the films under the action of alternating electric field. Produced by vibration. The noise of the film capacitor does not affect its quality of use and life.

Noise solution for film capacitors:

1 See if all the physical characteristics of the electronic device are correct.

2 regionalization No matter which kind of circuit has regional functions, it is not necessary to check one to prevent the problem from expanding.

3 Measure different instruments according to different functions.

The above three points, whether it is strong or weak, are applicable. Purchasing film capacitors needs to find quality manufacturers, the purpose is to ensure that their own capacitors will not have problems, pre-sales and after-sales service is guaranteed!
