电解电容保质期多久，需要从两个方面来分析，包括电解电容存放的时间和使用寿命。凡是按照正确的使用方法使用的话，电解电容的使用寿命都会比较长。

　　The shelf life of electrolytic capacitor should be analyzed from two aspects, including the storage time and service life of electrolytic capacitor. The service life of electrolytic capacitor will be longer if it is used correctly.

　　电解电容的使用寿命

　　Service life of electrolytic capacitor

　　①常见像铝电解电容这一些的电容寿命就很显而易见，因电解电容里面是电解液属于每次使用就会损耗一点电解液，像电解电容这一类的电容器使用寿命可以达到3-5年就算是高端品了，如果可以达到10年的电解电容那就更加的非常罕见的使用寿命了。

　　Common capacitor life such as aluminum electrolytic capacitor is very obvious. Because electrolytic capacitor contains electrolyte, it will lose a little electrolyte every time it is used. Capacitor like electrolytic capacitor can have a service life of 3-5 years, even if it is a high-end product. If the electrolytic capacitor can reach 10 years, it will be even more rare.

　　②像瓷介电容这一类电容可以说使用寿命非常的久，直接就是10年起步的使用寿命了，不过这类电容就要取决于它的质量了，不然一旦被击穿就直接损坏了。

　　This kind of capacitor, such as ceramic capacitor, can be said to have a very long service life, which is 10 years starting. However, this kind of capacitor depends on its quality, otherwise it will be directly damaged once it is broken down.

　　③金属膜电容这类电容器，使用寿命完全采取使用的原材料，一般的普通原材料生产的出来的可能2-3年就会失效，好点的原材料生产的出来的可以高达10年之久的使用寿命

　　Metal film capacitor, the service life of this kind of capacitor completely adopts the raw materials used. If the ordinary raw materials are used, they may be invalid in 2-3 years, while those produced by better raw materials can have a service life as long as 10 years。

　　电容的存放环境会直接影响使用寿命，所以存在在适合的环境下才能保证电解电容的使用寿命。如何正确存在电解电容呢？

　　The storage environment of the capacitor will directly affect the service life of the electrolytic capacitor, so the service life of the electrolytic capacitor can only be guaranteed under the suitable environment. How to exist electrolytic capacitor correctly?

　　①仓库的环境，太过潮湿的这种的场地切记不可用，可能放不到几天电容的容量耐压都会受到影响，

　　In the warehouse environment, if it is too humid, remember not to use it. The capacitance and withstand voltage of the capacitor may be affected in a few days,

　　②太过干燥的也不可以使用，因为电容里面的的原材料本身属于可燃物，如果温度较高也有可能发生自燃的现象。

　　Too dry can not be used, because the raw material in the capacitor itself is combustible, if the temperature is high, there may be spontaneous combustion phenomenon.

　　③存放环境一定要避免跟空气接触，这里说的空气接触是有些电容器没有包装袋的东西，会自己暴露在，久而久之的话就会被空气氧化腐蚀，直接影响到电解电容的寿命。

　　The storage environment must avoid contact with air. The air contact here means that some capacitors without packaging bags will be exposed by themselves. Over time, they will be oxidized and corroded by the air, which will directly affect the life of the capacitor.
