电子设备用双层固定电容器.第2部分:分规范:电力应用的双层电容器

[中文适用范围]： IEC 62391的本部分适用于电力应用的双电层电容器。电源用双电层电容器适用于需要放电电流在mA至A范围内的应用。电容器的特性包括相对较高的电容量和较低的内阻等性能，适用于测量分类的Class 3 IEC 62391-1 中指定。功率密度的定义及其计算程序应符合附录A的规定。 [外文原描述]： IEC 62391-2:2006 applies to electric double-layer capacitors for power application. Electric double-layer capacitors for power are intended for applications that require discharge currents in the range from mA to A. The characteristics of the capacitors include such performance as relatively high capacitance and low internal resistance, which is applicable to Class 3 of the measurement classification specified in IEC 62391-1. The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC 62391-1 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level; lower performance levels are not permitted.
