IEC 60384-6-2005 pdf – Fixed capacitors for use in electronic equipment – Part 6: Sectional specification – Fixed metallized polycarbonate film dielectric d.c. capacitors.
1 General 1.1 Scope This part of IEC 60384 applies to fixed capacitors for direct current with metallized electrodes and polycarbonate dielectric for use in electronic equipment. These capacitors may have “self-healing properties” depending on conditions of use. They are primarily intended for applications where the a.c. component is small with respect to the rated voltage. Two performance grades of capacitors are covered, Grade 1 for long-life application and Grade 2 for general application. Capacitors for electromagnetic interference and connection to the supply mains are not included but are covered by IEC 60384-14. 1.2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

1.3 Information 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 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. NOTE The information given in 1.3.1 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. 1.3.1 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 be stated in millimetres. Normally, the numerical values shall be given for the length of the body, the width and height of the body and the wire spacing, or, for cylindrical types, the body diameter and the length and 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 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 capacitor. When the capacitor is not designed for use on printed boards, this shall be clearly stated in the detail specification.
1.3.2.3 Soldering The detail specification shall prescribe the test methods, severities and requirements applicable for the solderability and the resistance to soldering heat test. 1.3.3 Marking The detail specification shall specify the content of the marking on the capacitor and on the package. Deviations from 1.5 of this specification shall be specifically stated. 1.4 Terms and definitions For the purposes of this document, the terms and definitions of IEC 60384-1, as well as the following, apply. 1.4.1 performance grade 1 capacitors (long-life) capacitors for long-life applications with stringent requirements for the electrical parameters 1.4.2 performance grade 2 capacitors (general purpose) capacitors for general application where the stringent requirements for Grade 1 capacitors are not necessary 1.4.3 rated voltage maximum d.c. voltage which may be applied continuously to a capacitor at the rated temperature
