20、Commission (IEC) 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
21、and in addition 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 Commit
22、tee interested 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 acco
23、rdance with conditions 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 in
24、terested IEC National 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 respo
25、nsible for the 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 divergenc
26、e between any 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
27、 of conformity. 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
28、and members of 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 Publi
29、cation or any 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 Publi
30、cation may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60368-3 has been prepared by lEC Technical Committee 49: Piezoelectric, dielectric and electrostatic devices and associated materials for frequency
31、control, selection and detection. This fourth edition cancels and replaces the third edition published in 2001 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) four enclosure types (CF05, CF06, CF07 and C
32、F09) have been deleted from previous edition, IEC 60368-3 Ed. 3.0; b) now standardized enclosures are totally 16 types. These are listed in Table.1. 4 60368-3 IEC:2010 The text of this standard is based on the following documents: CDV Report on voting 49/887/CDV 49/905A/RVC Full information on the v
33、oting 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, Part 2. A list of all parts of IEC 60368 under the general title Piezoelectric filters of assessed quality can be fo
34、und on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated 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, withd
35、rawn, replaced by a revised edition, or amended. 60368-3 IEC:2010 5 PIEZOELECTRIC FILTERS OF ASSESSED QUALITY Part 3: Standard outlines and lead connections 1 Scope This part of IEC 60368 specifies the outline drawing for piezoelectric filters with lead enclosures. 2 Guidance for the standardization
36、 of outline drawings for frequency control and selection devices In order to achieve a uniform presentation of all outline 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 o
37、f an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the same outline. Enlarged detailed 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 letter) as shown in Figure 1 below
38、 with applicable notes, if necessary. 2.2.2 A tabular listing relating to the drawing symbols to the actual dimensions. 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 projecti
39、on. 2.4 The function and identification of the lead connections (termination) shall be determined by agreement between 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
40、 body of the drawing. 2.6 All dimensions shall be in millimeters. 2.7 0utline dimensions A, B, C, D and E shall be listed 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 T
41、he spacing of the leads (termination) symbol H shall be listed with minimum, nominal and maximum dimensions. 2.10 Leads (terminations) for soldering application shall be specified with the minimum length dimensions (symbol L) only. Lead (termination) for plug-in application shall be specified with m
42、inimum and maximum length dimensions. 6 60368-3 IEC:2010 2.11 If leads (terminations) are provided with an undercut dimensions U and W shall be listed with minimum dimensions only.
