What are the shortcomings in the use of metallized film capacitors

Metallized film capacitors have the development of the whole electronic industry. In theory, there is no short circuit failure in the use of this material, but there will be a lot of short circuit failure in the use of capacitors, which increases customers' concern about the products. Although metallized film capacitors is a lot of advantages, but there are also some shortcomings.

The capacity stability of metallized film capacitors is not as good as that of other capacitors, mainly because the metallized capacitors will be lost because of the discomfort of the working environment in the process of long-term use, and even after self-healing, the capacity of the materials will become very small. Therefore, the environment used is very important, the stability of electricity is also required in the process of use, and the capacitance of metal foil sample can better meet the demand.

In the process of using metallized film capacitors, it is easy to have poor current ability, which is because in the process of working, the film layer of metallized film capacitors is relatively thin, and the current capacity of metal film capacitors is relatively weak, so this problem can be solved reasonably. The double-sided metallized film capacitors can meet the ideal demand, and further increasing the thickness of the metal coating can make up for the instability of capacitance in the process of use, as well as the phenomenon of poor current capacity.

Although metallized film capacitors have many advantages, but there are also disadvantages, so we must pay attention to.
