21、C) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in additio

22、n to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

23、 in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with co

24、nditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC N

25、ational Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the

26、 way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any

27、IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity

28、. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of

29、 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any

30、other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be

31、the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60679-3 has been prepared by IEC technical committee 49: Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control, selec

32、tion and detection. This third edition cancels and replaces the second edition issued in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: CO 01, CO 07, CO 10, CO 17 and CO 18 were deleted; The

33、 current pin layout of CO 06 was deleted. And new pin layout of CO 06 was added as CO 40; New layout of CO 15 was added as CO 41; Two new enclosures, CO 42 and CO 43 were added. Therefore revised edition includes 15 types of enclosures as in Table 1 of Clause 5. 4 60679-3 IEC:2012 The text of this s

34、tandard is based on the following documents: FDIS Report on voting 49/1009/FDIS 49/1021/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives,

35、 Part 2. A list of all parts of the IEC 60679 series, published under the general title Quartz crystal controlled oscillators of assessed quality, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated

36、 on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60679-3 IEC:2012 5 QUARTZ CRYSTAL CONTROLLED OSCILLATORS OF ASSESSED QUALITY Part 3: Standard o

37、utlines and lead connections 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 u

38、niform presentation of outline drawings for frequency control and selection devices, the following shall be considered. a) An outline drawing shall show all dimensional and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the

39、same outline. Enlarged and detailed view may be used, if necessary. b) The outline drawing shall consist of three parts: 1) A drawing with dimensional symbols (capital letter) as shown in Figure 1 with applicable footnotes, if necessary. 2) A tabular listing relating to the drawing symbol to the act

40、ual dimensions. Where possible, this shall be shown on the same page as the drawing. 3) An “actual-size“ sketch (scale 1:1). c) The outline drawing shall be executed in the third-angle projection. d) The function and identification of the lead connections (termination) shall be determined by agreeme

41、nt between the supplier and user. They shall not be defined on the outline drawing. e) Descriptive footnotes may be used at the bottom of/ or adjacent to, the drawing with proper reference to the body of the drawing. f) All dimensions shall be in millimeters. g) 0utline dimensions A, B, C, D and E s

42、hall be listed with maximum values only. h) If there are plural identical enclosures with different height (C), C shall be expressed with a suffix number such as C1, C2, etc. The following letter and number after the basic type number (four digits) indicate the enclosure height and lead length. The

43、identity references are given in the table in the sheet. i) Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum values. If applicable, nominal dimensions may be added. j) The spacing of the leads (termination) symbol H shall be listed with minimum, nominal and maxi

44、mum dimensions. 6 60679-3 IEC:2012 E D C L H U W K A B Actual size IEC 2461/12 1 2 Figure 1 Guidance for outline drawings Scale 2:1 Sheet number Ref. Dimensions (mm) Footnotes Min. Nom. Max.
