IEC 60384-18 pdf download Fixed capacitors for use in electronic equipment – Part 18: Sectional specification – Fixed aluminium electrolytic surface mount capacitors with solid (MnO 2 ) and non-solid electrolyte
This part of lEC 60384 applies to fixed aluminium electrolytic surface mount capacitors withsolid ‘(MnO,) and non-solid electrolyte primarily intended for d.c. applications for use inelectronic equipment.
The object of this standard is to prescribe preferred ratings and characteristics and to selectfrom IEc 60384-1 the appropriate quality assessment procedures，tests and measuringmethods and to give general performance requirements for this type of capacitor. Testseverities and requirements prescribed in detail specifications referring to this sectionalspecification should be of equal or higher performance level, because lower performance levelsare not permitted.

1.4lnformation to be given in a detail specification
Detail specifications shall be derived from the relevant blank detail specification.
Detail specifications shall not specify requirements inferior to those of the generic, sectional orblank detail specification. When more severe requirements are included, they shall be listed in1.9 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 specification and the values quoted shallpreferably be selected from those given in the appropriate clause of this sectional specification.
1.4.1Outline drawing and dimensions
There shall be an illustration of the capacitor as an aid to easy recognition and for comparisonof the capacitor with others. Dimensions and their associated tolerances，which affectinterchangeability and mounting, shall be given in the detail specification.All dimensions shallpreferably be stated in millimetres; however,when the original dimensions are given in inches,the converted metric dimensions in millimetres shall be added.
Normally, the numerical values shall be given for the length of the body, the width and height ofthe body and the wire spacing, or for cylindrical types, the body diameter, and the length anddiameter of the terminations. When necessary，for example，when a number of items(capacitance values/voltage ranges) are covered by a detail specification, the dimensions andtheir associated tolerances shall be placed in a table below the drawing.
When the configuration is other than described above, the detail specification shall state suchdimensional information as will adequately describe the capacitor. When the capacitor is notdesigned for use on printed boards, this shall be clearly stated in the detail specification.
