When more severe requirements are included, they shall be listed in 1.9 of the detail specification a
26、nd 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 appr
27、opriate clause of this sectional specification. 1.3.1 Outline drawinq and dimensions There shall be an illustration of the inductor as an aid to easy recognition and for comparison of the inductor with others. Dimensions and their associated tolerances, which affect interchangeability and mounting,
28、shall be given in the detail specification. All dimensions shall be stated in mm. Normally the numerical values shall be given for the length, the width and height of the body. When necessary, for example when a number of items (sizes and inductance ranges) is covered by a detail specification, the
29、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 inductor. 1.3.2 Mount inq The detail specification shall gi
30、ve guidance on method of mounting for normal use. Mounting or test and measurement purposes (when required) shall be in accordance with 4.1. 1.3.3 Ratinss and characteristics The ratings and characteristics shall be in accordance with the relevant clauses of this specification, together with the fol
31、lowing: (1) Rated inductance ranqe See 2.2.1 Note: When products approved to the detail specification have different ranges, the following statement should be added: “The range of inductance values available in each size is given in the current CECC O0 200 (Register of Firms, Products and Services A
32、pproved under the CECC System) “ .

33、 detail specification shall specify the content of the marking on the inductor and on the package. Deviations from 1.5 shall be specifically stated. 1.4 Terminoloav In addition to the applicable terms and definitions of CECC 29 O00 (EN 129 000:1993) the following definitions apply: 1.4.1 Surface mou
34、ntina inductor An inductor whose small dimensions and nature or shape of terminations make it suitable for surface mounting on hybrid circuits or printed boards. 1.4.2 Performance made 1 inductors (long life) Inductors for long-life applications with stringent: requirements for the electrical parame
35、ters. 1.4.3 Performance arade 2 inductors (general purpose) Inductors for general application, where the stringent require- ments for grade 1 inductors are not necessary. 1.4.4 Rated current (IR) The maximum r.m.s. value of the current, at which an inductor may be operated continuously at the rated
36、temperature. Note: The current may consist of d.c. current only, a.c. current only or of a combination of both. For testing purposes d.c. current is mandatory. High frequencies require a reduction of current in regard to temperature rise by magnetic and skin effect losses. 1.4.5 Incremental current
37、(IcR) That value of polarising direct current which when superimposed on the alternating measuring current will cause a reduction in measured inductance value of 10 %.

39、e 6) Rated current 7) Climatic category 8) Reference to the detail specification 9) CECC Mark 1.5.2 When the detail specification requires marking the inductors shall be clearly marked with as many as possible of the above items as is considered useful. Any duplication of information in the marking
40、on the inductor should be avoided. If coded marking is applied, the codes as given in IEC xxx (at present 51(Sec)257) shall be used. 1.5.3 The package containing the inductor(s) shall be clearly marked with all the information listed in 1.5.1. 1.5.4 Any additional marking shall be so applied that no
41、 confusion can arise.

42、8-1. The lower and upper category temperature and the duration of the damp heat, steady state test shall be chosen from the following: Lower category temperature: - 55 OC, - 40 OC, - 25 OC upper category temperature: + 85 OC, + 100 OC, + 125 OC and + 150 OC Duration of the damp heat, steady state te
43、st: 4, 10, 21 and 56 days - Note: With continuous operation at 125 OC in excess of the endurance test time, accelerated ageing has to be considered (see detail specification) . The severities for the cold and dry heat tests are the lower and the upper category temperatures respectively. 2.2 Preferre
44、d values of ratinas 2.2.1 Rated inductance (LR) Preferred values of rated inductance are: 1 - 1,2 - 1,5 - 1,s - 2,2 - 2,7 - 3,3 - 3,9 - 4,7 - 5,6 - 6,s - and 8,2 and their decimal multiples. These values conform to the E 12 series of preferred values given in IEC 63: Preferred number series for resi
45、stors and capacitors. 2.2.2 Tolerance on rated inductance The preferred tolerance on rated inductance is I 10 %. If other.tolerances are required they shall be preferably either f 5 % or f 20 %.

49、cribed in the detail specification and when requested by a purchaser. After the endurance test the parameters for which variables information is required are the inductance, Q, resonant frequency and the d.c. resistance. 3.4 Qualification approval The procedures for qualification approval testing are given in 3.4 of CECC 29 000. The schedule to be used for qualification approval testing on the basis of lot-by-lot and periodic tests is given in 3.5 of this specification. The procedure using a fixed sample size schedule is given in 3.4.1 and 3.
