Full title and description
High frequency inductive components — Non-electrical characteristics and measuring methods — Part 1: Fixed, surface mounted inductors for use in electronic and telecommunication equipment (IEC 62025-1:2007). This edition defines terms, dimensional nomenclature, recommended standard values and dimensions, letter coding for inductance values and guidance on operating temperature ratings for fixed surface-mounted inductors and ferrite beads used in high-frequency applications.
Abstract
IEC 62025-1:2007 (Edition 2) provides standardized non‑electrical specifications and guidance for fixed, surface-mounted inductors and ferrite beads intended for electronic and telecommunication equipment. The document establishes terminology, dimensional nomenclature and recommended standard values and sizes, and introduces a letter-code system for inductance values plus updated operating temperature ratings. It is intended to harmonize component data and simplify procurement, interchangeability and mechanical design.

Scope
This part applies to fixed, surface-mounted inductors and ferrite beads used in electronic and telecommunication equipment. It establishes non‑electrical requirements, defines terms and dimensional nomenclature, gives recommendations for standard values and dimensions, provides a letter-code table for inductance values and supplies guidance on operating temperature ratings. The document is concerned with physical/configurational and non‑electrical characteristics rather than electrical performance parameters; specific test methods for non‑electrical characteristics are covered in the companion Part 2.
Key topics and requirements
- Definitions and standardized terminology for high-frequency SMD inductive components.
- Nomenclature of dimensions and recommended mechanical drawings and tolerances.
- Recommended standard values and dimension series for fixed surface-mounted inductors and ferrite beads.
- Letter-code system for indicating inductance values in component marking and documentation.
- Classification of operating temperature ratings and guidance on temperature-related markings.
- Guidance for relating these non-electrical requirements to detail (product) specifications and manufacturer data.
- Reference to test-methods and reliability standards (testing procedures are addressed in IEC 62025-2 and related documents).
Typical use and users
Used by component manufacturers, product design engineers, component procurement and quality teams, test laboratories and standards committees. Typical tasks include defining mechanical and marking requirements for SMD inductors, preparing component detail specifications, ensuring interchangeability across manufacturers, and aligning product datasheets with internationally recognized dimensional and coding practices.
Related standards
Notable related and companion documents include IEC 62025-1:2002 (previous edition), IEC 62025-2 (test methods for non-electrical characteristics; later editions published), IEC 62024 series (electrical characteristics and measuring methods), IEC 62211 (reliability/performance references), and EN/CENELEC adoptions of IEC 62025-1:2007. Users should consult the later parts and current IEC publications for updated test methods and electrical measurement requirements.

FAQ
Q: What is this standard?
A: IEC 62025-1:2007 is an IEC international standard (Edition 2) that specifies non-electrical requirements, terminology, dimensional nomenclature and recommended standard values/dimensions for fixed surface-mounted inductors and ferrite beads used in electronic and telecommunication equipment.
Q: What does it cover?
A: It covers definitions, mechanical/dimensional nomenclature, recommended sizes and standard values, a letter-code for inductance marking, and guidance on operating temperature ratings. It addresses non-electrical (mechanical/marking/classification) aspects rather than detailed electrical test procedures.
Q: Who typically uses it?
A: Component manufacturers, electronics design engineers, procurement and quality assurance teams, and test laboratories use the standard to specify and verify mechanical and marking requirements and to ensure component interchangeability.
Q: Is it current or superseded?
A: IEC 62025-1:2007 was officially withdrawn (withdrawal effective 25 April 2025). It is no longer current; users should consult the IEC webstore and relevant TC‑51 publications and companion documents (for example IEC 62025-2 and related IEC/EN publications) for current requirements and test methods.
Q: Is it part of a series?
A: Yes. IEC 62025 is a multi-part series addressing non-electrical characteristics and measuring methods for high-frequency inductive components. Part 1 addresses fixed SMD inductors (this document), Part 2 covers test methods for non-electrical characteristics, and related IEC/EN standards cover electrical characteristics and other measurement subjects.
Q: What are the key keywords?
A: SMD inductors; ferrite beads; high-frequency inductive components; non-electrical characteristics; dimensions; inductance code; operating temperature; IEC 62025.
