Description (English):

IEC 60384-24:2021 applies to fixed tantalum electrolytic surface mount capacitors with conductive polymer solid electrolyte, which are primarily intended for DC applications for use in electronic equipment. The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1:2016 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. This edition includes the following significant technical changes with respect to the previous edition: - Revision of the structure in accordance with ISO/IEC Directives, Part 2:2018, to the extent practicable, and harmonization between other similar kinds of documents. - In addition, Clause 5 and all the tables have been reviewed in order to prevent duplications and contradictions.

Abstract

Overview

IEC 60384-24:2021 is the IEC sectional specification for fixed tantalum electrolytic surface-mount capacitors with conductive polymer solid electrolyte. It applies to these fixed capacitors primarily intended for DC applications in electronic equipment. The document prescribes preferred ratings and characteristics, selects applicable quality assessment procedures, and defines tests and measurement methods (referencing IEC 60384-1:2016 where appropriate). The 2021 edition aligns structure with ISO/IEC Directives, Part 2:2018 and updates Clause 5 and tables to remove duplications and contradictions.

Key topics and requirements

The standard lays out practical and technical requirements for surface-mount tantalum capacitors using conductive polymer solid electrolytes, including:

Preferred ratings and characteristics: nominal capacitance, tolerance, rated and category voltages, surge voltages and rated temperatures.
Test and measurement procedures: standardized methods for:
- leakage current, capacitance and tangent of loss angle (tan δ)
- equivalent series resistance (ESR) where applicable
- resistance to soldering heat and solderability
- mechanical tests: shear, substrate bending
- environmental tests: rapid temperature change, climatic sequence, damp heat (steady and cyclic), high/low temperature characteristics
- electrical stress tests: surge voltage, high surge current (if required), endurance
- storage at high temperature and solvent resistance (as required)
Quality assurance: qualification approval procedures, lot-by-lot and periodic inspection plans, sampling and assessment levels.
Marking and documentation: capacitor marking, packaging information, and detail-specification data elements required for procurement and design.

Applications and who uses this standard

IEC 60384-24:2021 is essential for stakeholders involved with surface-mount tantalum capacitors in electronic systems:

Capacitor manufacturers - for product specification, testing, and conformity to international performance and reliability expectations.
Component engineers and PCB designers - to select appropriate capacitor ratings (voltage, capacitance, ESR) and ensure soldering and thermal robustness for DC circuits.
Quality assurance and test laboratories - to implement standardized test procedures and lot qualification/inspection regimes.
Purchasing and compliance teams - to verify supplier documentation and ensure components meet IEC sectional and referenced general requirements.
Certification bodies and product safety assessors - for evidence of standardized testing and traceable quality assessment.
