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.
lnternational Standard IEC 61837-1 has been prepared by IEC technical committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency
control, selection and detection.
This second edition cancels and replaces the first edition published in 1999. It is a technical
revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• one enclosure type (SIP-L5/01) has been deleted;
• Configuration symbol of enclosures is currently consolidated into one as DCC (dual chip
carrier).
– 4 – 61837-1 © IEC:2012
The text of this standard is based on the following documents:
CDV Report on voting
49/930/CDV 49/969/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 lnternational Standard shall be read in conjunction with IEC 61240:1994. IEC 61240:1994
deals with standard outlines and terminal lead connections as they apply to SMDs for frequency
control and selection in plastic moulded enclosures.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the IEC 61837 series, published under the general title Surface mounted
piezoelectric devices for frequency control and selection – Standard outlines and terminal lead
connections, can be found on the IEC web site.
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.

STANDARD OUTLINES AND TERMINAL LEAD CONNECTIONS –

Part 1: Plastic moulded enclosure outlines

1 Scope
This part of IEC 61837 deals with standard outlines and terminal lead connections as they apply
to SMDs for frequency control and selection in plastic moulded enclosures and is based on
IEC 61240.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments)
applies.
IEC 61240: 1994, Piezoelectric devices – Preparation of outline drawings of surface-mounted
devices (SMD), for frequency control and selection – General rules
3 Configuration of enclosures
These enclosures are made of plastic moulded materials with the terminal leads based on the
descriptive designation system for semiconductors, devices package.
The configuration symbols are shown as follows:
– DCC (dual chip carrier)
4 Designation of types
The designation of types is shown in four parts as follows:

A B C D D’
A: Configuration symbol of enclosures:
– DCC (dual chip carrier);
B: Structure of terminal leads:
– J: leaded type;
C: Number of terminal leads
D: Two digit serial number
___________
A new edition is under consideration.

5 Plastic moulded enclosure dimensions
The dimensions in this standard apply to all the completed SMD-devices for frequency control
and selection. Only those dimensions are given which meet the requirements of IEC 61240.
6 Lead connections
Recommendations for the lead connections of all completed SMD-devices for frequency control
and selection are given in the following individual sheets. Lead connections shall always be
given in the detail specification.
7 Plastic moulded enclosures
The following table sets out the designation of the plastic moulded enclosures as outlined in the
ensuing specification sheets.
