What electrolytic capacitors fear most is that in the working environment of high temperature and high humidity, especially in the power supply, the electronic components with excessive heat are often too close to the electrolytic capacitors due to improper design, resulting in the electrolytic capacitors are very easy to be damaged. What will be the impact of too high or too low temperature when the electrolytic capacitors are working?

 

　　1、电解电容的工作温度范围是多少？

　　What is the working temperature range of electrolytic capacitor?

　　电解电容的种类有很多，它的耐温范围有一定的区别，主要包括：

　　There are many types of electrolytic capacitors, and their temperature resistance ranges are different, mainly including:

　　高品质的是-40℃~150℃，-40℃~125℃，标准品一般是在-40℃~105℃、-40℃~85℃。

　　The high quality is - 40 ℃~150 ℃, - 40 ℃~125 ℃, and the standard is generally - 40 ℃~105 ℃, - 40 ℃~85 ℃.

　　一般购买电容器的时候，规格书上面都标注有电解电容的工作温度范围。

　　Generally, when purchasing capacitors, the operating temperature range of electrolytic capacitors is marked on the specifications.

　　2、电解电容温度过低会怎么样？

　　What if the temperature of electrolytic capacitor is too low?

　　电解电容能在-40℃的环境下工作，正常情况下，我们很难找到这么低的工作环境，所以可以以这样理解，电解电容不用担心温度过低的影响。

　　The electrolytic capacitor can work at - 40 ℃. Normally, it is difficult to find such a low working environment, so it can be understood that the electrolytic capacitor does not have to worry about the impact of low temperature.

　　3、电解电容温度过高会怎么样？

　　What if the temperature of electrolytic capacitor is too high?

　　电解电容损坏一般都是因为温度过高造成的，比如电解电容旁边有发热量很大的电子元器件，或者整个电路发热量很大，散热效果差，电器在太阳暴晒、高温、高湿环境下工作，都容易导致电解电容温度过高而损坏。

　　The electrolytic capacitor is generally damaged due to high temperature. For example, there are electronic components that generate a lot of heat near the electrolytic capacitor, or the entire circuit generates a lot of heat and has poor heat dissipation effect. Electrical appliances working in the sun, high temperature and high humidity environment are likely to cause the electrolytic capacitor to be damaged due to high temperature.

　　如果电解电容器长期在高于其允许的温度下运行，会加速电解电容器的热老化。电解电容的寿命就会明显降低，一般表现是温度越高，电解电容的寿命越短，温度特别高时，电解电容的寿命就会急剧减。

　　If the electrolytic capacitor operates at a temperature higher than its allowable temperature for a long time, the thermal aging of the electrolytic capacitor will be accelerated. The life of the electrolytic capacitor will be significantly reduced. Generally, the higher the temperature is, the shorter the life of the electrolytic capacitor will be. When the temperature is particularly high, the life of the electrolytic capacitor will be dramatically reduced.
