鋁電解電容的使用范圍比較廣泛，在使用過程中有幾點是需要特別注意的。

　　Aluminum electrolytic capacitor is widely used, and several points need special attention in the process of use.

　　1.鋁電解電容器分正負極，不應(yīng)加反向電壓或交流電壓。對可能出現(xiàn)反向電壓的電路，應(yīng)選擇無極性電容器。注意：即使無極性電容器，也不能直接用于交流電路。

　　Aluminum electrolytic capacitor is divided into positive and negative poles, and reverse voltage or AC voltage shall not be applied. For the circuit that may have reverse voltage, the non-polar capacitor should be selected. Note: even nonpolar capacitors cannot be directly used in AC circuits.

　　2.對需要快速充放電的電路，不能使用鋁電解電容器，而應(yīng)選擇特別設(shè)計的具有較長壽命的電容器。

　　For the circuit which needs fast charge and discharge, aluminum electrolytic capacitor should not be used, but the capacitor with long life should be selected.

　　3.不應(yīng)使用超載電壓。

　　Overload voltage should not be used.

　　4.直流電壓和紋波電流疊加后的峰值電壓不應(yīng)超過額定工作電壓。

　　The peak voltage after superposition of DC voltage and ripple current should not exceed the rated working voltage.

　　5.若兩個以上電容器串聯(lián)，應(yīng)確保施加電壓低于額定值，而且要并聯(lián)一個平衡電阻，以使每個電容器所加電壓相等。

　　If more than two capacitors are connected in series, make sure that the applied voltage is lower than the rated value, and a balance resistor should be connected in parallel to make the voltage of each capacitor equal.

　　6.電容器使用溫度與壽命的關(guān)系

　　Relationship between service temperature and service life of capacitor

　　請勿讓電容器使用超出電容器最高工作溫度，電容器的壽命取決于使用溫度，一般狀況下使用溫度每降低10℃，預期壽命延長一倍，故盡可能在低溫下使用電容器。

　　Do not extend the service life of the capacitor by 10 ℃ according to the service life of the capacitor.
