25、Sectional specification Fixed polyethylene-terephthalate film dielectric metal foil d.c. capacitors 1 General 1.1 Scope This part of IEC 60384 applies to fixed direct current capacitors, for rated voltages not exceeding 6 300 V, using as dielectric a polyethylene-terephthalate film and electrodes of

26、 thin metal foils. For capacitors with rated voltages exceeding 1 000 V, additional tests and requirements may be specified in the detail specification. The capacitors covered by this standard are intended for use in electronic equipment. NOTE Capacitors for radio interference suppression are not in

27、cluded, but are covered by IEC 60384-14 (see bibliography). 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 requirem

28、ents 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, because lower performance levels are not permitted. 1.3 Normative references The following referenced documen

29、ts 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. IEC 60062, Marking codes for resistors and capacitors IEC 60063, Preferred number

32、y 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 1.4.1 may, for

33、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 Outline drawing and dimensions There shall be an illus

34、tration 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, howe

35、ver, 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 height of the body and the wire spacing, or for cylindrical types, the body diameter, and the l

36、ength 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 desc

37、ribed 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. 1.4.2 Mounting The detail specification shall specify the

38、method of mounting to be applied for normal use and for the application of the vibration and the bump or shock tests. The capacitors shall be mounted by their normal means. The design of the capacitor may be such that special mounting fixtures are required in its use. In this case the detail specifi

39、cation shall describe the mounting fixtures and they shall be used in the application of the vibration and bump or shock tests. 1.4.3 Ratings and characteristics The ratings and characteristics shall be in accordance with the relevant clauses of this specification, together with the following: 1.4.3

40、.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 values available in each voltage range is given in the qualified products list“. 1.4.3.2 Particular characteristics Additional c

41、haracteristics may be listed, when they are considered necessary to specify adequately the component for design and application purposes. 1.4.3.3 Soldering The detail specification shall prescribe the test methods, severities and requirements applicable for the solderability and the resistance to so

42、ldering heat test. BS EN 60384-11:2008 6 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 of this sectional specification, shall be specifically stated. 1.5 Terms and definitions For the purposes of this document
