What may cause the failure of film capacitor?
When film capacitors are exposed to high temperature and high humidity environment for a long time, the capacitor is easy to fail. The main reason for the damage of film capacitors is that the molecules have strong diffusion ability, and the dielectric constant of water is large, and the loss is also large, which leads to the sharp deterioration of the electrical properties of the capacitor, such as the decrease of insulation resistance and withstand voltage, and the dielectric loss angle. Tangent increases and capacitance changes. Especially when the ambient temperature increases, the diffusion ability of water molecules increases. Therefore, the high temperature and high humidity environment (such as 85°C, 85% RH) has a greater impact on the electrical properties of the capacitor, resulting in an increase in the product failure rate, reducing film capacitor’s reliability and damage.
In addition, the loss of film capacitors is related to the manufacturing process. If the production process is not control strictly, there will be problems such as dielectric, mechanical damage, pinholes, and low cleanliness. Therefore, it is very important for us to choose a film capacitor manufacturer with guaranteed quality. In order to avoid purchasing film capacitors produced by small workshops, be sure to understand the manufacturer's information before purchasing.
