23、UBLE-LAYER CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT Part 2: Sectional specification Electric double-layer capacitors for power application 1 General 1.1 Scope This part of IEC 62391 applies to electric double-layer capacitors for power application. Electric double-layer capacitors for power are in
24、tended 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
25、 definition of power density and its calculating procedure should be in accordance with Annex A. 1.2 Object 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
26、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. 1.3 Normative references The
27、following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60063, Preferred number series for resistors and
