IEC 60384-20-2015 pdf download.Fixed capacitors for use in electronic equipment – Part 20: Sectional specification – Fixed metallized polyphenylene sulfide film dielectric surface mount d.c. capacitors.
This part of IEC 60384 applies to fixed surface mount capacitors for direct current, with metallized electrodes and polyphenylene sulfide dielectric for use in electronic equipment.
These capacitors have metallized connecting pads or soldering strips and are intended to be mounted directly onto substrates for hybrid circuits or onto printed boards. They may have “self-healing properties” depending on conditions of use and are primarily intended for applications where the a.c. component is small with respect to the rated voltage.
These capacitors are divided to 3 grades. Performance grade 1 for long life, performance grade 2 for general purpose and performance grade 3 for miniature type. Capacitors for radio interference suppression are not included, but are covered byIEC 60384-1 4.
Capacitors used for motor or fluorescent lamp are outside the scope of this standard.
1 .2 Object
The object of this standard 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 standard shall be of equal or higher performance level, lower performance levels are not permitted.
1 .3 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

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 standard.
1 .4.2 Outline drawing and dimensions There shall be an illustration of the capacitor as an aid to easy recognition and for comparison of the capacitor 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.IEC 60384-20 pdf download.
