How to choose aluminum electrolytic capacitor and film capacitor?

In exactly the same application, is aluminum electrolytic capacitor or thin film capacitor used? The trend in the future must be to use thin-film capacitors. The advantages of using thin-film capacitors include the following four aspects:

1. aluminum electrolytic capacitor is a liquid capacitor. First of all, it has a service life limit. Now many end-users of solar
and wind energy products have a service life requirement of more than 15 years. The product must be reliable within 15 years, because the maintenance cost of wind energy products is very expensive and difficult. Thin film capacitor is a solid
capacitor, which can just meet this requirement. Aluminum electrolytic capacitor has volatilization of electrolyte materials.
Generally, it cannot reach the service life of 15 years. If it wants to reach the test life of 15 years, it means that it
needs to be replaced two to three times during this period.

1. the second advantage is that due to the characteristics of the dielectric material of the film capacitor, its ESR value is
low, so its heating capacity is also very low. In addition, it can also achieve very high ripple voltage resistance. 3. the
third feature is that it has a wider range of ambient temperature, which is also the difference between liquid capacitors and solid capacitors. Thin film capacitors have very good stability at low temperature.

1. the filtering ability of thin film capacitor is many times stronger than that of aluminum capacitor. If the filter is good,
the film capacitor can be used, and the conversion efficiency is higher. This is the development trend of wind energy and
solar energy application.

In addition, in the application of solar energy, because the charging and discharging times of super capacitor can reach hundreds of thousands of times, the life characteristics are far better than other battery products, which can solve the worry of maintenance free, especially in high altitude and closed state. Therefore, super capacitor is often used as an energy storage device to replace the traditional lead-acid battery. The charging life of the traditional lead-acid battery is generally about 500 times. For example, solar street lights and traffic lights are examples of applications.

Of course, the new energy industry will not only bring market demand to the high-voltage, high-capacity electrolytic capacitor, film capacitor and super capacitor industries, but also bring new growth to the demand for other conventional capacitors. The application in the field of new energy, in addition to the author's examples, there are also numerous cases of specific application in other occasions.
