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. NOTE The information given in 1.4.1 may, for convenience, be presented in tabular form. The fol
28、lowing 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. 1.4.1 Outline drawing and dimensions There shall be an illustration of the surface mount capacitors as an aid
29、to easy recognition and for comparison of the surface mount capacitors with others.

All dimensions shall preferably be stated in millimetres; however, when the origin
30、al dimensions are given in inches, the converted metric dimensions in millimetres shall be added. Normally, the numerical values shall be given for the length, width and height of the body. When necessary, for example, when a number of case sizes are covered by a detail specification, the dimensions
31、 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 describe the surface mount capacitors. 1.4.2 Mounting The detail specification sha

36、inations make it suitable for surface mounting 1.6 Marking See 2.4 of IEC 60384-1 with the following details: 1.6.1 The information given in the marking is normally selected from the following list; the relative importance of each item is indicated by its position in the list: a) polarity of the ter
37、minations (unless identified by the construction); b) rated capacitance; c) rated voltage (d.c. voltage may be indicated by the symbol or ); d) tolerance on rated capacitance; e) year and month (or week) of manufacture; f) manufacturers name or trade mark; g) climatic category; h) manufacturers type
38、 designation; i) reference to the detail specification. 1.6.2 Surface mount capacitors are generally not marked on the body. If some marking can be applied, they shall be clearly marked with as many as possible of the above items as is considered useful. Any duplication of information in the marking
39、 on the capacitor should be avoided. 1.6.3 Any marking shall be legible and not easily smeared or removed by rubbing with the finger. 1.6.4 The package containing the capacitor(s) shall be clearly marked with all the information listed in 1.6.1, except polarity, unless this is applicable to the meth
