Piezoelectric devices - Preparation of outline drawings of surface-mounted devices (SMD) for frequency control and selection - General rules (IEC 61240:2016)
This International Standard sets out general rules for drawing all dimensional and geometrical
characteristics of a surface-mounted piezoelectric device package (referred to in this document
as SMD) in order to ensure mechanical inter-changeability of all outline drawings of the SMDs
for frequency control and selection.

Dispositifs piézoélectriques - Préparation des dessins d'encombrement des dispositifs à montage en surface pour la commande et le choix de la fréquence - Règles générales (IEC 61240:2016)
L'IEC 61240:2016 établit les règles générales pour dessiner toutes les caractéristiques dimensionnelles et géométriques des boîtiers de dispositifs piézoélectriques pour montage en surface (appelés CMS, composants pour montage en surface, dans le présent document) afin d'assurer l'interchangeabilité mécanique avec tous les autres dessins d'encombrement des dispositifs pour montage en surface pour la commande et le choix de la fréquence. La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- les dessins d’encombrement en trois vues, (de dessus, de face et de dessous) ont été modifiés pour être conformes à la méthode de projection du troisième dièdre de l'ISO. La vue de droite a donc été ajoutée aux vues de dessus, de face et de dessous;
- les dimensions des lignes de référence et les dimensions géométriques du boîtier pour les enveloppes ont été modifiées pour une utilisation pratique;
- les informations sur les enveloppes céramiques sans fils de sortie miniaturisées des dispositifs piézoélectriques pour montage en surface (CMS) pour la commande et le choix de la fréquence ont été incluses dans une annexe.
Piezoelektrični elementi - Priprava tehničnih risb površinsko montiranega elementa (SMD) za frekvenčno regulacijo in filtriranje - Splošna pravila (IEC 61240:2016)
Ta mednarodni standard postavlja splošna pravila za risanje dimenzionalnih in geometričnih karakteristik paketov površinsko montiranih piezoelektričnih elementov (v nadaljevanju SMD), da zagotovi mehanično zamenljivost vseh tehničnih risb površinsko montiranih piezoelektričnih elementov za frekvenčno regulacijo in filtriranje.

PIEZOELECTRIC DEVICES – PREPARATION OF OUTLINE
DRAWINGS OF SURFACE-MOUNTED DEVICES (SMD) FOR
FREQUENCY CONTROL AND SELECTION – GENERAL RULES
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 61240 has been prepared by lEC technical committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control,
selection and detection.
This third edition cancels and replaces the second edition published in 2012. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• outline drawings have been changed from three views (top, front and bottom) to that based
on ISO layout in the third-angle projection, in which the view from the right has been added
to the top, front and bottom views;
• reference line and geometrical dimensions of the package for enclosures have been
changed for practical use;
• information on miniaturized leadless ceramic enclosures of piezoelectric devices (SMD) for
frequency control and selection has been included in an annex.

INTRODUCTION
The enclosures of quartz crystal resonators and oscillators are unified in this third edition of
IEC 61240.
Regarding the current situation of many quartz crystal device suppliers, many of them use their
own enclosure layouts in their catalogues. For the convenience of consumers, general rules of
enclosure layout and definition of size need to be unified.
The reasons prompting the revision of IEC 61240:2012 are as follow
...
