電解電容器的使用壽命與什么因素有關(guān)呢？根據(jù)長(zhǎng)期的實(shí)踐經(jīng)驗(yàn)總結(jié)出電解電容器的使用壽命與其工作環(huán)境的溫度有著直接的關(guān)系。

　　What factors are related to the service life of electrolytic capacitors? According to the long-term practical experience, it is concluded that the service life of capacitor is directly related to the temperature of working environment.

　　普通的電解電容器在環(huán)境溫度為90℃時(shí)已經(jīng)損壞。但是現(xiàn)在有很多種類(lèi)的電解電容器的工作環(huán)境溫度已經(jīng)很高在環(huán)境溫度為90℃，通過(guò)電解電容器的交流電流和額定脈沖電流的比為0.5時(shí)，壽命仍然為10000h，但是如果溫度上升到95℃時(shí)，電解電容器即已經(jīng)損壞。

　　The common electrolytic capacitor has been damaged when the ambient temperature is 90 ℃. But now there are many kinds of electrolytic capacitors with high working environment temperature. When the ambient temperature is 90 ℃, the ratio of AC current passing through the electrolytic capacitor to rated pulse current is 0.5, the service life is still 10000h. However, if the temperature rises to 95 ℃, the electrolytic capacitor will be damaged.

　　在選擇電容器的時(shí)候，應(yīng)該根據(jù)具體的環(huán)境溫度和其它的參數(shù)指標(biāo)來(lái)選定，如果忽略了環(huán)境溫度對(duì)電容器壽命的影響，那么電源工作的可靠性、穩(wěn)定性將大大降低，甚至損壞設(shè)備和儀器。就一般情況而言，電解電容器工作在環(huán)境溫度為80℃時(shí)，一般能達(dá)到10000h壽命的要求。

　　When selecting capacitors, the specific environmental temperature and other parameters should be selected. If the influence of environmental temperature on capacitor life is ignored, the reliability and stability of power supply will be greatly reduced, and even the equipment and instruments will be damaged. Generally speaking, the electrolytic capacitor can reach the life requirement of 10000 h when the ambient temperature is 80 ℃.

　　溫度越高，電容器的壽命越短。所以在選擇電解電容型號(hào)的時(shí)候一定要注意其所能承受的工作溫度，以及適宜的工作溫度，在適宜的溫度下工作，才能更好的延長(zhǎng)電解電容的使用時(shí)間。

　　The higher the temperature, the shorter the life of the capacitor. Therefore, in the selection of electrolytic capacitor model, we must pay attention to the working temperature it can bear, and the appropriate working temperature, and work under the appropriate temperature, in order to better extend the use time of electrolytic capacitor.

　　電解電容器的壽命還與電容器長(zhǎng)時(shí)間工作的交流電流與額定脈沖電流，一般是指在85℃的環(huán)境溫度下測(cè)試值，但是有一些耐高溫的電解電容器是在125℃時(shí)測(cè)試的數(shù)據(jù)的比值有關(guān)。一般說(shuō)來(lái)，這個(gè)比值越大，電解電容器的壽命越短，當(dāng)流過(guò)電解電容器的電流為額定電流的3.8倍時(shí)，電解電容器一般都已經(jīng)損壞。所以，電解電容器有它的安全工作區(qū)，對(duì)于一般應(yīng)用，當(dāng)交流電流與額定脈沖電流的比值在3.0倍以下時(shí)，對(duì)于壽命的要求已經(jīng)滿足。

　　The service life of electrolytic capacitor is also related to the AC current and rated pulse current of capacitor working for a long time, which generally refers to the test value under the ambient temperature of 85 ℃. However, some electrolytic capacitors with high temperature resistance are related to the ratio of test data at 125 ℃. Generally speaking, the higher the ratio, the shorter the life of electrolytic capacitor. When the current flowing through the electrolytic capacitor is 3.8 times of the rated current, the electrolytic capacitor is generally damaged. Therefore, the electrolytic capacitor has its safe working area. For general applications, when the ratio of AC current to rated pulse current is less than 3.0 times, the requirements for service life have been met.

　　由此可見(jiàn)，電解電容的使用壽命主要取決于工作溫度和交流電流與額定脈沖電流兩個(gè)因素，確定好這兩個(gè)工作因素之后，再選擇合適的電解電容才能有效的推進(jìn)后續(xù)的工作。

　　It can be seen that the service life of electrolytic capacitor mainly depends on the working temperature and AC current and rated pulse current. After these two working factors are determined, the appropriate electrolytic capacitor can effectively promote the follow-up work.
