In the development of new energy, thin film capacitor has always been the point of concern, so where is the advantage of thin film capacitor compared with aluminum electrolytic capacitor in new energy? Let's look down with xiaobian. Hope the content of this article can help you!
1. Aluminum electrolytic capacitors are liquid capacitors. First of all, they have a service life. Film capacitors are solid capacitors, which can just meet this use requirement. Aluminum electrolytic capacitors have the volatilization of electrolytic liquid materials. Generally, it cannot reach the service life of 15 years.
2. The second advantage is that, due to the characteristics of the dielectric material of the film capacitor, its ESR value is low, so its calorific value is very low, in addition, it can also achieve high voltage resistance.
3. Feature three, it has a wider range of ambient temperature, which is the difference between liquid and solid capacitors. Film capacitors have very good stability at low temperature.
4. The filtering ability of film capacitors is many times stronger than that of aluminum capacitors. If the filtering is better, a film capacitor can be used for higher conversion efficiency. This is the trend in the development of wind and solar energy applications.
