Overview
IEC TS 61994-4-3:2008 is a technical specification developed by the International Electrotechnical Commission (IEC) that defines the terminology for materials used in dielectric devices, specifically targeting waveguide type dielectric resonators. These materials represent the state-of-the-art in frequency control and selection technology. The document provides standardized terms and definitions essential for manufacturers, researchers, and engineers working with piezoelectric and dielectric devices within the scope of IEC Technical Committee 49.
This specification is part of the IEC 61994 series focused on piezoelectric and dielectric devices for frequency control and selection, offering a glossary that aids in maintaining consistency and clarity across international standards and documentation.
Key Topics
Dielectric Materials
Materials that predominantly exhibit dielectric properties, crucial for constructing high-performance parts in frequency control devices.Dielectric Resonator Materials
Specialized dielectric materials designed to be used in resonators operating at ultra-high frequencies (UHF) or super high frequencies (SHF). These materials require:- High relative permittivity
- Low loss factor
- Minimal temperature coefficient of permittivity
Electrical Properties
- Electric Constant (ε0): A fundamental constant defining the permittivity of vacuum.
- Relative Permittivity (εr): Ratio of absolute permittivity of a material to the electric constant. Includes the dielectric constant and dielectric loss.
- Loss Factor (tan δ): Ratio representing energy dissipation within the material.
- Quality Factor (Q): Indicates the efficiency of the material in terms of energy loss, essential for high-frequency applications.
Thermal Properties
- Temperature Coefficient of Permittivity (TCε): Measures how permittivity changes with temperature, critical for device stability.
- Coefficient of Linear Thermal Expansion (α): Describes dimensional changes with temperature, impacting resonator precision.
Device Components
- Dielectric Resonators: These are waveguide structures made from high dielectric constant materials and are typically shielded with conductive materials.
- Dielectric Supports: Elements used to hold dielectric resonators; generally made of materials with low dielectric constants to minimize interference.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
