Parameters to be paid attention to in selecting film capacitors

Film capacitor manufacturers should pay attention to the selection of capacitors: rated voltage. The rated voltage refers to the voltage applied to the two ends of the capacitor when the capacitor is able to work normally, stably and reliably in a certain period of time in the circuit. The rated voltage of film capacitors is not only related to the structure of dielectric and capacitor used by capacitors, but also to the environment of capacitors. When the frequency and temperature rise, the rated voltage will drop.

So when going to the film capacitor manufacturer to select film capacitors, we should pay attention to the rated voltage of the capacitors, taking temperature factors as an example to illustrate. If the temperature is not controlled in an environment, the temperature will rise very much, then the film capacitor should be applied to the capacitor with a slightly higher rated voltage than the actual demand, so as to ensure the normal, stable and reliable use of the capacitor.

After reading this article, when choosing film capacitors, you can start with rated voltage.
