電解電容保質期多久，需要從兩個方面來分析，包括電解電容存放的時間和使用壽命。凡是按照正確的使用方法使用的話，電解電容的使用壽命都會比較長。

　　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.

　　電解電容的使用壽命

　　Service life of electrolytic capacitor

　　①常見像鋁電解電容這一些的電容壽命就很顯而易見，因電解電容里面是電解液屬于每次使用就會損耗一點電解液，像電解電容這一類的電容器使用壽命可以達到3-5年就算是高端品了，如果可以達到10年的電解電容那就更加的非常罕見的使用壽命了。

　　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像瓷介電容這一類電容可以說使用壽命非常的久，直接就是10年起步的使用壽命了，不過這類電容就要取決于它的質量了，不然一旦被擊穿就直接損壞了。

　　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金屬膜電容這類電容器，使用壽命完全采取使用的原材料，一般的普通原材料生產的出來的可能2-3年就會失效，好點的原材料生產的出來的可以高達10年之久的使用壽命

　　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。

　　電容的存放環境會直接影響使用壽命，所以存在在適合的環境下才能保證電解電容的使用壽命。如何正確存在電解電容呢？

　　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倉庫的環境，太過潮濕的這種的場地切記不可用，可能放不到幾天電容的容量耐壓都會受到影響，

　　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太過干燥的也不可以使用，因為電容里面的的原材料本身屬于可燃物，如果溫度較高也有可能發生自燃的現象。

　　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存放環境一定要避免跟空氣接觸，這里說的空氣接觸是有些電容器沒有包裝袋的東西，會自己暴露在，久而久之的話就會被空氣氧化腐蝕，直接影響到電解電容的壽命。

　　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.
