30、tallized polyphenylene sulfide film dielectric surface mount d.c. capacitors 1 General 1.1 Scope This part of IEC 60384 is applicable to fixed surface mount capacitors for direct current, with metallized electrodes and polyphenylene sulfide dielectric for use in electronic equipment. These capacitor
31、s have metallized connecting pads or soldering strips and are intended to be mounted directly onto substrates for hybrid circuits or onto printed boards. These capacitors may have “self-healing properties“ depending on conditions of use. They are primarily intended for applications where the a.c. co
32、mponent is small with respect to the rated voltage. Capacitors for radio interference suppression are not included, but are covered by IEC 60384-14. 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 as
33、sessment 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 sectional specification shall be of equal or higher performance level, lower performance le
34、vels are not permitted. 1.3 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.

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 as
39、terisk. 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 shall preferably be selected from those given in the appropriate clause of this sectional specification. 1.4.1 Ou
40、tline 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 dimens
41、ions shall preferably 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, width and height of the body. When necessary, for example when a numb
42、er of items (sizes and capacitance/voltage ranges) is 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 informatio
43、n as will adequately describe the capacitor. 1.4.2 Mounting The detail specification shall give guidance on methods of mounting for normal use. Mounting for test and measurement purposes (when required) shall be in accordance with 4.1. 1.4.3 Ratings and characteristics The ratings and characteristic
44、s shall be in accordance with the relevant clauses of this specification, together with the following. 1.4.3.1 Rated capacitance range See 2.2.1. NOTE When products approved to the detail specification have different ranges, the following statement should be added: “The range of capacitance values a
45、vailable in each voltage range is given on the IEC online service, www.iecq.org/certificates.“ 1.4.3.2 Particular characteristics Additional characteristics may be listed, when they are considered necessary to specify adequately the component for design and application purposes. 1.4.3.3 Soldering Th
46、e detail specification shall prescribe the test methods, severities and requirements applicable for the solderability and the resistance to soldering heat tests. 1.4.4 Marking The detail specification shall specify the content of the marking on the capacitor and on the package. Deviations from 1.6 s
