QUARTZ CRYSTAL UNITS OF ASSESSED QUALITY –

Part 3: Standard outlines and lead connections


FOREWORD
1) The International Electrotechnical 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 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 Committee 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 accordance 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
interested 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 responsible 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 divergence 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 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 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 Publication 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 Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60122-3 has been prepared by IEC Technical Committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency
control, selection and detection.
This fourth edition cancels and replaces the third edition published in 2001. This fourth edition
constitutes a technical revision.
The main changes with respect to the previous edition are as follows:
– 12 of the 48 enclosure types contained in the previous edition have been deleted.

The text of this standard is based on the third edition and the following documents:
CDV Report on voting
49/886/CDV 49/904/RVC

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, Part 2.
A list of all parts of IEC 60122 series, published under the general title, Quartz crystal units 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 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.

INTRODUCTION
The third edition of IEC 60122-3 (2004) contained 48 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, the following 12 enclosure types have been deleted from the third edition
of lEC 60122-3.
AA, AB, BC, BC/1, BF, BF/1, CX, CY, CY/1, CZ, DA, DC.
Therefore, this new version (the fourth edition) contains the following 36 enclosure types ; CK,
CM, CN, CP, DK, DL, DP, EH, DQ, DR, DZ, DV, DW, ED, EB, EJ, EK, CU 01A, CU 01B, CU
01C, CU 01D, CU 01E, CU 01F, CU 02A, CU 02B, CU 02C, CU 02D, CU 02E, CU 02F

QUARTZ CRYSTAL UNITS OF ASSESSED QUALITY –

Part 3: Standard outlines and lead connections



1 Scope
This part of IEC 60122 specifies the outline drawing for quartz crystal units with lead
enclosures.
2 Guidance for the standardization of outline drawings for frequency control
and selection devices
2.1 General
In order to achieve a uniform presentation of all outline drawings for frequency control and
selection devices the following guide shall be considered:
2.2 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 outline. Enlarged detailed view may be used, if necessary.
2.3 The outline drawing shall consist of three parts:
2.3.1 A drawing with dimensional symbols (capital letter) as shown in Figure 1 below with
applicable notes, if necessary.
2.3.2 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.
2.3.3 An "actual-size" sketch (scale 1:1).
2.4 The outline drawing shall be executed in the third angle projection.
2.5 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.
2.6 Descriptive notes may be used at the bottom of/ or adjacent to, the drawing with proper
reference to the body of the drawing.
2.7 All dimensions shall be in millimeters.
2.8 Outline dimensions A, B, C, D and E shall be listed with maximum values only.
2.9 Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum
values. If applicable, nominal dimensions may be added.
2.10 The spacing of the leads (termination) – symbol H – shall be listed with minimum,
nominal and maximum dimensions.
