Part 2: Ceramic enclosures
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 61837-2 has been prepared by IEC technical committee 49:

Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control,

selection and detection.

This bilingual version (2018-11) corresponds to the monolingual English version, published in

2018-05.
This third edition cancels and replaces the second edition published in 2011 and
Amendment 1:2014. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) revision of the figures to match the notation of the drawings of IEC 61240:2016;

b) addition of 7 enclosures as follows: DCC-6/5032A, DCC-6/3225A, DCC-4/3215C,
DCC-6/2016A, DCC-2/2012C, DCC-2/1610C, DCC-4/1210C.
---------------------- Page: 6 ----------------------
IEC 61837-2:2018 © IEC 2018 – 5 –

As a result, this third edition contains a total of 45 enclosure types, which are listed in Table 1.

This International Standard is to be read in conjunction with IEC 61240:2016.
The text of this International Standard is based on the following documents:
CDV Report on voting
49/1252/CDV 49/1276/RVC

Full information on the voting for the approval of this International Standard can be found in the

report on voting indicated in the above table.
The French version of this standard has not been voted upon.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts in 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 website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

OUTLINES AND TERMINAL LEAD CONNECTIONS –
Part 2: Ceramic enclosures
1 Scope

This part of IEC 61837 deals with standard outlines and terminal lead connections as they apply

to surface-mounted devices (SMD) for frequency control and selection in ceramic enclosures,

and is based on IEC 61240:2016.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies.

For undated references, the latest edition of the referenced document (including any

amendments) applies.

devices (SMD) for frequency control and selection – General rules
3 Terms and definitions
No terms and definitions are listed in this document.

ISO and IEC maintain terminological databases for use in standardization at the following

addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
4 Configuration of enclosures

The enclosures of the surface-mounted devices are made of ceramic materials with the

terminals of deposited metal film (leadless type) based on a descriptive designation system for

semiconductors – devices packages.
The configuration symbols are shown as follows:
• DCC (dual chip carrier);
• QCC (quad chip carrier).
5 Designation of types
The designation of types is shown on four parts as follows:

– QCC (quad chip carrier).
B: Structure of terminal leads: leadless type has no mark.
C: Number of terminal leads
D: Serial number of both figures
E: Arrangement of terminal land:
In the case of DCC types:

– A (arrangement in the width direction side or the width direction side and the corner);

– B (arrangement in the length direction side or the length direction side and the corner);

– C (arrangement in the corner only).
In the case of QCC types:
– A (arrangement in the side only);
– B (arrangement in the side and the corner).
6 Ceramic enclosure dimensions

The dimensions given in this document apply to all completed SMD-devices for frequency

control and selection. Only those dimensions which meet the requirements of IEC 61240 are

given.
