IEC 62025-2:2019

Overview

IEC 62025-2:2019 - "High frequency inductive components - Non-electrical characteristics and measuring methods - Part 2: Test methods for non-electrical characteristics" is the IEC international standard that specifies mechanical test methods for surface-mounted device (SMD) inductors used in electronic and telecommunication equipment. Edition 2.0 (2019) is a technical revision of the 2005 edition and focuses exclusively on non‑electrical (mechanical) performance measurement. It complements reliability specifications referenced in IEC 62211.

Key topics and technical requirements

This part of IEC 62025 defines standardized procedures and test conditions for measuring mechanical performance of SMD inductors, including:

• Body strength testing (pressurizing/jig methods) to verify mechanical integrity of the inductor body.
• Robustness of terminations (electrodes), including resistance to PCB bending and adherence tests referenced to IEC 60068-2-21.
• Solderability and preconditioning/recovery procedures for SMD devices, with immersion and reflow alternatives.
• Resistance to soldering heat and to dissolution of metallization, with specified preconditioning and measurement sequences.
• Vibration and shock testing procedures for mechanical durability under environmental stress.
• Annex A: practical guidance on mounting SMD inductors on test printed‑circuit boards (land patterns, soldering, preheating, cleaning).

The standard cites normative references (e.g., IEC 60068 series, IEC 60068-2-58, IEC 60068-2-21, IEC 60068-2-6, IEC 60068-2-27, IEC 61188-5-2) and was updated by revision of Table 5 and normative references in this edition.

Applications and who uses it

IEC 62025-2 is essential for organizations involved in the design, manufacture, testing and procurement of high-frequency SMD inductors:

• Component manufacturers use it to define internal QC and to produce compliant datasheets and detail specifications.
• Test laboratories implement its test methods for certification, incoming inspection and failure analysis.
• OEMs and contract manufacturers reference it for supplier qualification, PCB assembly process validation and reliability planning.
• Quality and compliance engineers rely on it to harmonize mechanical testing across supply chains and to reduce field failures in electronic and telecommunication equipment.

Using IEC 62025-2 helps ensure consistent mechanical performance validation for SMD inductors, improving product reliability and interoperability.
