IEC 60384-26:2018 pdf download.Fixed capacitors for use in electronic equipment – Part 26: Sectional specification – Fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte
1 General
1 .1 Scope
This part of IEC 60384 applies to fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte primarily intended for d.c. applications for use in electronic equipment. Fixed aluminium electrolytic capacitors with solid (MnO 2 ) electrolyte are covered by IEC 60384-4. Fixed aluminium electrolytic surface mount capacitors with conductive polymer solid electrolyte are covered by IEC 60384-25.
1 .2 Object
The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1 , 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, because lower performance levels are not permitted.

1 .4 Information to be given in a detail specification
1 .4.1 General Detail specifications shall be derived from the blank detail specification. Detail specifications shall not specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe 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. The information given in 1 .4.2 may, for convenience, be presented in tabular form. The following information shall be given in each detail specification and the values quoted shall preferably be selected from those given in the appropriate clause of this sectional specification. 1 .4.2 Outline drawings and dimensions There shall be an illustration of the capacitors as an aid to easy recognition and for comparison of the 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 dimensions in millimetres shall be added.
1 .4.3 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 or shock tests. The design of the capacitor may be such that special mounting fixtures are required in its use. In this case, the detail specification shall describe the mounting fixtures and they shall be used in the application of the vibration and bump or shock tests. 1 .4.4 Rating and characteristics 1 .4.4.1 General The ratings and characteristics shall be given in accordance with the relevant subclauses of this sectional specification, including the items specified in 1 .4.4.2 to 1 .4.4.4. 1 .4.4.2 Nominal capacitance range See 2.2.1 . When products approved to the detail specification have different nominal capacitance ranges, the following statement should be added:
