1. 直流电解电容是有极性的。 DC electrolytic capacitors are polarized. |
2. 确定极性，极性标志在电容器的基体上。以免因极性反可能引起电路短路或电容器损坏， 当极性不固定或不确定的，使用无极性电容器。注意直流电容器不能使用于交流。 Make sure of the polarity. The polarity is marked to on the body of the capacitor .Application of the reversed voltage cause a short circuit or damage the capacitor. Use bipolar capacitors when the polarity is not determined or unknown. Note that DC electrolytic capacitors can not be used for AC application. |
3. 使用电压不要大于额定电压。 Do not apply voltage Higher than rated voltage. |
| 4. 使用电压大于额定电压，漏电流会增大，可能损坏电容器。建议工作电压为额定电压的70%-80%，电容器在建议工作电压下使用可以延长电容器的寿命。 | | If a voltage exceeding the rated voltage is applied, the leakage current will increase, which damage the capacitor. Recommended working voltage is 70 to 80 percent of tatted voltage. Using capacitors at recommended working voltage prolongs capacitor life. |
|
| 5. 不要使用过量纹波电流通过电容器。 Do not allow excessive ripple current through the capacitor. |
6. 流过电容器的纹波电流超过许可值，将会引起电容器发热，电容量减少，损耗电容器。通过电容器的纹波电流不要大于允许值。 The flow of ripple current over permissible ripple current will cause heat of the capacitor, which may decrease the capacitance and damage the capacitor. Ripple current on the capacitor must be at or bellow allowable level. |

7. 快速充放点电路中，使用专门设计的电容器。 Use specially designed capacitors for the circuits where charge and discharge are frequency repeated. |
8. 在经受快速的周期性充放电电路中，电容器可能收到损害，它的寿命因容量下降、温升等原因而缩短，在这种电 路中，一定要使用专门设计的电容器。 In the circuit subjected to rapid charge cycles, capacitors may be damaged, its life may be shortened by capacitance decrease, heat rise, ect. Be sure and use special capacitors in these applications. |
9. 工作温度范围。 Operating temperature range. |
10. 电容器的特性随工作温度变化而变化，在温度较高的情况下，容量，漏电流增大，损耗减少；在低温情况下，容量和漏电流下降，损耗增大。电容器在较低温度下使用会确保延长寿命。 The characteristics of capacitors change with the operating temperature. The capacitance and leakage current increase and tgδ decrease at higher temperatures. The capacitance and leakage current decrease and tgδ at increase lower temperature. Usage at lower temperature will ensure longer life. |
11. 核对工作频率。 Check operating frequency. |
| |
12. 电解电容器的容量通常是在100HZ或者120HZ下测得的。然而要记住容量随频率的升高而下降，tanδ随频率的升高而增大，并使周围温度升高。| The capacitance of electrolytic capacitors is usually measured at 100Hz or 120Hz. However, remember that capacitance decrease and tgδ increase as the applied frequency becomes higher whereas the ambient temperature becomes higher. |
|
| 13. 长时间存放的电容器，在使用前加额定直流电压处理。 | | Apply rated DC voltage treatment to the capacitors which have been stored for a long time. |
14. 长时间的存放，实际对电容器的容量和tanδ没有多大的影响，然而往往会使漏电流增大，耐压降低。长时间存放后的电容器处理，首先逐渐施加直流电压至额定电压，然后再使用。| Long periods of storage have virtually no effect on a capacitor’s capacitance and tgδ. Such periods tend however, to increase leakage current and decrease withstand voltage. After removing capacitors from long-duration storage, first apply a gradually increasing DC voltage to rated voltage and then use them. | | | | 15. 固態电容器的外殻為镀膜外殼, 与極性是绝缘的。The Case of Conductive Polymer Aluminum Solid Electrolytic Capacitor is Resin coated case which is insulated with the terminals. |
