When a thin film capacitor is used in a wet environment, the surface of the film capacitor is gradually condensed with water, which increases the leakage current of the film capacitor and leads to an increase in the loss of the capacitor. If the moisture on the surface of the film capacitor or the water in the surrounding environment enters the inside of the capacitor, the metal in the capacitor will be oxidized and corroded, and the loss of the film capacitor will be increased.
The same external lead of capacitor is oxidized or corroded will also increase the loss of thin film capacitor. Therefore, the use of thin film capacitors should be guaranteed to dry, moisture-proof environment. In the use of thin film capacitors when the ambient temperature we should pay attention to, this can ensure that the film capacitor normal life time Oh!
