Selection of parameters for thin Film Capacitor

Film capacitor manufacturers should pay attention to the selection of capacitors: rated voltage. The so-called rated voltage refers to the voltage applied to the two ends of the capacitor by the film capacitor which can work normally, stably and reliably within a certain period of time in the circuit. The rated voltage of a thin film capacitor is not only related to the dielectric and device structure used by the capacitor, but also to the environment in which the capacitor is located. When the frequency and temperature rise, the rated voltage will decrease.

Therefore, the film capacitor manufacturers should pay attention to the film capacitor voltage rating, temperature factors as an example to explain. If the temperature is not controlled in the environment, the temperature will often rise very badly, then the application of film capacitor should select the rated voltage slightly higher than the actual requirements of the capacitor to ensure the normal, stable, reliable use of capacitors.

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