FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation 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, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, 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.
International Standard IEC 1240 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:
DIS Report on voting
49/278/RVD
49(CO)276
Full information on the voting for the approval of this standard can be found in the report
on voting indicated in the above table.

General rules
1 General
1.1 Scope and object
This International Standard sets out general rules for drawing all dimensional and geo-
metrical characteristics of a surface-mounted piezoelectric device package (referred to
in this standard as SMD) in order to ensure mechanical interchangeability of all outline
drawings of the SMDs for frequency control and selection.
1.2
Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this International Standard. At the time of publication, the
editions indicated were valid. All normative documents are subject to revision, and parties
to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated
below. Members of IEC and ISO maintain registers of currently valid International
Standards.

2 Classification of SMD
The SMD piezoelectric devices are classified into three types of packages depending on
the structure of the terminal leads.
a) Leaded type: the folded ends of the terminal leads are turned away from the body.
b) Fol
