23、2006 3 FIXED ELECTRIC DOUBLE-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 cap

24、acitors 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 speci

25、fied in IEC 62391-1. The 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 an

26、d 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. 1.3 N

Detail specifications shall not specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe

31、 requirements are included, they shall be listed in 1.9 of the detail specification and indicated in the test schedules, for example by an asterisk. NOTE The information given in 1.4.1 may, for convenience, be presented in tabular form. The following information shall be given in each detail specifi

32、cation and the values quoted shall preferably be selected from those given in the appropriate clause of this sectional specification. 1.4.1 Outline drawing and dimensions There shall be an illustration of the surface mount capacitors as an aid to easy recognition and for comparison of the surface mo

33、unt capacitors with others. Dimensions and their associated tolerances, which affect interchangeability and mounting, shall be given in the detail specification. All dimensions shall preferably be stated in millimetres; however, when the original dimensions are given in inches, the converted metric

34、dimensions in millimetres shall be added. Normally, numerical values shall be given for the length of the body, the width and height of the body and wire spacing, or, for cylindrical types, the body diameter and length, and the length and diameter of the terminations. When necessary, for example, wh

35、en a number of case sizes are covered by a detail specification, the dimensions and their associated tolerances shall be placed in a table below the drawing. When the configuration is other than described above, the detail specification shall state such dimensional information as will adequately des

36、cribe the capacitor. When the capacitor is not designed for use on printed boards, this shall be clearly stated in the detail specification. 1.4.2 Mounting The detail specification shall specify the method of mounting to be applied for normal use and for the application of the vibration and the bump

37、 or shock test. The capacitors shall be mounted by their normal means. The design of the capacitor may be such that special mounting fixtures are required for its use. In this case, the detail specification shall describe the mounting fixtures and they shall be used in the application of the vibrati

38、on and bump or shock tests. 1.4.3 Rating and characteristics The ratings and characteristics shall be in accordance with the relevant clauses of this specification, together with the following. 1.4.3.1 Rated capacitance range See 2.2.1. NOTE When products approved to the detail specification have di

39、fferent ranges, the following statement should be added: “The range of capacitance values available in each voltage range is given in IEC QC 001005.” EN 62391-2:2006 5 1.4.3.2 Particular characteristics Additional characteristics may be listed, when they are considered necessary to specify adequatel

40、y the component for design and application purposes. 1.4.3.3 Soldering The detail specification shall prescribe the test methods, severities and requirements applicable to the solderability and the resistance to soldering heat tests. 1.4.4 Marking The detail specification shall specify the content o

41、f the marking on the capacitor and on the package. Deviations from 1.6 of this sectional specification shall be specifically stated. 1.5 Terminology For the purposes of this document, the terms and definitions of IEC 62391-1, together with the following, apply. 1.5.1 surface mount capacitor capacito
