Advantages of film capacitor temperature characteristics

The good temperature characteristics of the film capacitor, unlike the other capacitors, are that the dielectric material is a high temperature polypropylene film, and its temperature characteristics allow it to swim back and forth between -40 ° C and 105 ° C without being affected. After measurement, the capacitance of the film capacitor and the electrolytic capacitor varies with temperature at a fixed frequency, and it can be analyzed that the gradual increase in temperature causes the capacitance of the film capacitor to decrease due to the decrease in the overall capacitance. However, the magnitude of the decline is small, almost negligible, and is maintained at about 300 PPM/°C. The capacitance of the electrolytic capacitor is different. It varies greatly with temperature at any temperature, about 200- 600PPM/°C. The temperature characteristics of film capacitors make it less demanding in the environment, whether it is in the extremely cold northeast, the hot Taklimakan Desert or some other natural environment.
