23、s amendment and supplement contained 52 enclosure types showing the dimensional and geometrical characteristics of these enclosures. Since its release, due to progress in technology, many of the enclosures given in the standard have become obsolete. Bearing this in mind, technical committee 49 has i
24、ssued a questionnaire on all outlines contained in IEC 60679-3. Based on the replies received, technical committee 49 made a decision at the meeting held in Rotterdam in June 1996 to retain only enclosures which remained in “wide usage”. These enclosures are specified in the present standard. The fo
25、llowing 25 enclosure types have been deleted from the first edition of 60679-3 (1989) and its amendment and supplement: CO 03 A1CO 04 A1CO 04 B1CO 05 A1CO 06 B.CO 06 C.CO 06 .1 CO 06 .2CO 07 B.CO 07 C.CO 07 D.CO 10 B1CO 11 A1CO 12 A1 CO 13 A1CO 13 B1CO 14 A1CO 15 A1CO 17 C1CO 18 A1CO 18 C1 CO 19 .2C

IEC:2001 5 QUARTZ CRYSTAL CONTROLLED OSCILLATORS OF ASSESSED QUALITY Part 3: Standard outlines and lead connections
27、1 Scope This part of IEC 60679 specifies the outline dimensions and lead connections for quartz crystal controlled oscillators with lead enclosures. 2 Guidance for the standardization of outline drawings for frequency control and selection devices In order to achieve a uniform presentation of all ou
28、tline drawings for frequency control and selection devices, the following guide shall be considered. 2.1 An outline drawing shall show all dimensional and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the same outlines. Enl
29、arged detail view may be used, if necessary. 2.2 The outline drawing shall consist of three parts: 2.2.1 A drawing with dimensional symbols (capital letters) as shown in figure 1 below with applicable notes, if necessary. 2.2.2 A tabular listing relating the drawing symbols to the actual dimensions.
30、 Where possible, this shall be shown on the same page as the drawing. 2.2.3 An “actual-size” sketch (scale:1:1). 2.3 The outline drawing shall be executed in the third-angle projection. 2.4 The function and identification of the lead connections (termination) shall be determined by agreement between
31、 the supplier and user. They shall not be defined on the outline drawing. 2.5 Descriptive notes may be used at the bottom of, or adjacent to, the drawing with proper reference to the body of the drawing. 2.6 All dimensions shall be in millimetres. 2.7 Outline dimensions A, B, C, D and E shall be lis
32、ted with maximum values only. 2.8 Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum values. If applicable, nominal dimensions may be added. 2.9 The spacing of the leads (termination) symbol H shall be listed with minimum, nominal and maximum dimensions. Page 5 EN

36、mensions of crystal oscillator enclosure The dimensions in this standard apply to the completed quartz crystal controlled oscillators. Only those dimensions which meet the requirements of the guidance for standardization of outline drawings are given (see clause 2). 4 Lead connections Recommendation
