IEC 60384-11 pdf download Fixed capacitors for use in electronic equipment – Part 11: Sectional specification – Fixed polyethylene-terephthalate film dielectric metal foil d.c. capacitors
Detail specifications shall not specify requirements inferior to those of the generic, sectionalor blank detail specification. When more severe requirements are included,they shall belisted in 1.9 of the detail specification and indicated in the test schedules, for example by anasterisk.
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 quotedshall preferably be selected from those given in the appropriate clause of this sectionalspecification.
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 heightof the body and the wire spacing,or for cylindrical types，the body diameter,and the lengthand diameter 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.
The detail specification shall specify the method of mounting to be applied for normal use andfor the application of the vibration and the bump or shock tests. The capacitors shall bemounted by their normal means. The design of the capacitor may be such that specialmounting fixtures are required in its use. In this case the detail specification shall describe themounting fixtures and they shall be used in the application of the vibration and bump or shocktests.
1.4.3Ratings and characteristics
The ratings and characteristics shall be in accordance with the relevant clauses of thisspecification, together with the following:
22.214.171.124 Rated capacitance rangeSee 2.2.1.
NOTE When products approved to the detail specification have different ranges,the following statement shouldbe added: “The range of values available in each voltage range is given in the qualified products list”.
Additional characteristics may be listed,when they are considered necessary to specifyadequately the component for design and application purposes.
