IEC 60384-1:2021

IEC 60384-1:2021 Overview

IEC 60384-1:2021 is an international standard published by the International Electrotechnical Commission (IEC) that provides a generic specification for fixed capacitors used in electronic equipment. This edition, the 6th, introduces a comprehensive restructuring to align with ISO/IEC Directives, Part 2, offering improved categorization and updated test methods tailored for quality assessment and specification development of fixed capacitors. It defines standard terminology, inspection procedures, and test methods essential for ensuring the reliability, safety, and performance of fixed capacitors in various electronic applications.

Key Topics Covered

• Scope and Definitions: Establishes clear terms, symbols, and units related to fixed capacitors, facilitating universal understanding and application.
• General Requirements: Specifies preferred values, marking protocols, and additional technical requirements critical for component identification and interoperability.
• Test Methods: Introduces a restructured classification of tests, including:
  • Electrical tests such as insulation resistance, voltage proof, capacitance, loss angle, ESR, leakage current, impedance, self-resonant frequency, and surge resistance.
  • Mechanical tests covering visual examination, termination robustness, vibration, shock, shear, and substrate bending.
  • Environmental and climatic assessments including rapid temperature changes, damp heat, endurance, and thermal stability.
  • Safety-related tests addressing passive flammability and pressure relief for specific capacitor types.
• Quality Assessment Procedures: Provides guidelines and procedures for qualification, capability, and technology approval to support manufacturing and reliability assurance.
• Annexes: Includes informative annexes on pulse testing guidance, detailed quality assessment frameworks, and a cross-reference to previous editions for ease of transition.
