General Information
Relations
Overview
IEC 60368-3:2010 is an international standard published by the International Electrotechnical Commission (IEC) that defines standard outlines and lead connections for piezoelectric filters of assessed quality. This part 3 of the IEC 60368 series focuses specifically on the outline drawings and lead enclosures for piezoelectric filters used in frequency control and selection devices. It provides uniform mechanical dimensions and leads configuration to ensure compatibility and interchangeability between components from different manufacturers.
This 2010 edition is the fourth revision of the standard and introduces key updates, including the deletion of four previously defined enclosure types and the formal listing of 16 standardized enclosure types, facilitating clearer specification and manufacturing consistency.
Key Topics
Outline Drawings Standardization:
The standard mandates a precise format for outline drawings of piezoelectric filters, including:- Dimension and geometric characteristics essential for mechanical interchangeability
- Use of third angle projection for all drawings
- Inclusion of detailed views where necessary
- Presentation of dimensions in millimeters with specified maximum, minimum, and nominal values depending on the measurement
Lead Connections and Enclosure Types:
The document specifies guidance for lead (termination) dimensions, including cross-sectional size, length, and spacing, to accommodate various applications:- Minimum and maximum dimensions for leads depending on whether they are for soldering or plug-in applications
- Identification of lead connections through an agreement between supplier and user, without embedding this info in the outline drawing itself
Enclosure Types and Dimensions:
- The standard now recognizes 16 types of enclosures for piezoelectric filters, replacing the prior extended list by deleting types CF05, CF06, CF07, and CF09.
- Detailed tables provide the exact dimensions for each enclosure type, covering metal enclosures (soldered and welded), number of leads, and physical sizes.
- These enclosures are designed to house piezoelectric components reliably while ensuring standardized form factors.
Applications
IEC 60368-3:2010 is highly relevant for manufacturers, designers, and quality assurance teams involved with piezoelectric filters, especially in contexts where frequency control and frequency selection components are critical such as:
- Radio frequency (RF) circuits in telecommunications
- Oscillator circuits requiring precise frequency stability
- Signal filtering in electronic communication devices
- Industrial sensing and measurement systems relying on piezoelectric components
By adhering to this standard, organizations ensure consistent mechanical compatibility across suppliers, simplifying integration, reducing design errors, and accelerating development cycles.

PIEZOELECTRIC FILTERS OF ASSESSED QUALITY –
Part 3: Standard outlines and lead connections
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.
