PRECAUTIONS AND GUIDELINES 式铝电解电容器应用指南 Application Guidelines For V-Chip Aluminum Electrolytic Capacitors 1．电路设计Circuit Design 1.1 请明确铝电解电容器所处的环境和安装条件应符合本说明书中规定的情况。Please make sure the environmental and mounting conditions to which the capacitor will be exposed to are within the conditions specified in this catalog (or alternat e Acons specifications, such as series drawings). 1.2 工作温度和纹波电流应小于本说明书中的规定。Operating temperature and applied ripple current must be within ACON S specification. l 电容器不能用于超过规定的环境温度。The capacitor must not be used in an ambient temperature which exceeds the operating temperature specified in this catalog. l 电容器不能用于超过规定的纹波电流。Do not apply excessive current which exceeds the allowable ripple current. 1.3 设计电路时 选择满足产品寿命的电容器。Appropriate capacitors which comply with the life requirement of the products should be selected when designing the circuit. 1.4 铝电解电容器是有极性的。不要施加反向电压或交流电。在可能出现电压极性相反的电路中， 使用无极性电容器。 注意：即使无极性电容器也不能在交流电情况下使用。Aluminum electrolytic capacitors are polarized. Do not apply reverse voltage or AC voltage. Please use non-polarized capacitors for a circuit that can possibly see reversed polarity. Note; Even non-polarized capacitors can not be used for AC voltage application. 1.5 在需要快速和频繁充放电的电路中，请不要使用铝电解电容器。它需要使用具有长寿命特征的特别设计的电容器。 Do not use aluminum electrolytic capacitors in a circuit that requires rapid and very frequent charge/discharge. In this type of circuit, it is necessary to use a special design capacitor with extended life characteristics. 1.6 不要施加过高的电压。Do not apply excess voltage. l 请注意， 流电压上叠加纹波电流时的峰值电压不要超过额定电压。Please pay attention so that the peak voltage, which is DC voltage overlapped by ripple current, will not exceed the rated voltage. l 在使用2 个以上的铝电解电容器串联时， 注意施加的电压应低于额定电压。应在每只电容器并联一只平衡电 阻，使每只电容器承受的电压相等。In the case where more than 2 aluminum electrolyti
