QUARTZ CRYSTAL CONTROLLED OSCILLATORS

Part 3: Standard outlines and lead connections
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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 and dielectric devices for frequency control and selection.
The text of this standard is based on the following documents:
FDIS Report on voting
49/495/FDIS 49/510/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 second edition cancels and replaces the first edition published in 1989, the first
supplement (1991) and amendment 1 (1994). This second edition constitutes a technical
revision.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annex A forms an integral part of this standard.

INTRODUCTION
The first edition of IEC 60679-3 (1989), its 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 issued 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 following 25 enclosure types have been deleted from the first edition of 60679-3 (1989)
and its amendment and supplement:

QUARTZ CRYSTAL CONTROLLED OSCILLATORS
OF ASSESSED QUALITY –
Part 3: Standard outlines 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 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 of an
enclosure necessary to ensure mechanical interchangeability with all other enclosures of the
same outlines. Enlarged 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. 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 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 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 The spacing of the leads (termination) – symbol H – shall be listed with minimum,
nominal and maximum dimensions.

2.10 Leads (terminations) for soldering applications shall be specified with the minimum
length dimensions (symbol L) only.
Leads (terminations) for plug-in applications shall be specified with minimum and maximum
length dimensions.
2.11 If leads (terminations) are provided with an undercut, dimensions U and W shall be
listed with minimum dimensions only.
3 Dimensions 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
Recommendations for the lead connections of quartz crystal controlled oscillators are given in
annex A to this standard. Lead connections shall always be given in the detail specification.
