Overview - IEC 60384-1:2016 (Fixed capacitors, Part 1: Generic specification)
IEC 60384-1:2016 is the international generic specification for fixed capacitors intended for use in electronic equipment. Edition 5.0 (2016‑02) defines standard terminology, inspection procedures and methods of test to be referenced by sectional and detail specifications for capacitor quality assessment, compliance testing and procurement. This edition introduces an INTRODUCTION, adds a new whisker growth test (4.41) and restructures Annex Q.
Keywords: IEC 60384-1, fixed capacitors, capacitor testing, generic specification, electronic equipment.
Key topics and technical requirements
The standard sets out a comprehensive set of technical topics and test procedures used to characterize and verify fixed capacitors, including:
- Terms, symbols and definitions - standardized vocabulary for capacitor parameters.
- Preferred values and marking - nominal capacitance, rated voltage and identification requirements.
- Quality assessment procedures - sampling, inspection and compliance paths.
- Electrical tests:
- Capacitance measurement and variation with temperature
- Tangent of loss angle and equivalent series resistance (ESR)
- Insulation resistance and leakage current
- Voltage proof and surge testing
- Impedance, self‑resonant frequency and inductance
- Mechanical and environmental tests:
- Robustness of terminations, solderability and resistance to soldering heat
- Vibration, shock, bump and rapid change of temperature
- Climatic sequence, damp heat (steady state and cyclic), storage at temperature extremes
- Endurance (life) testing and charge/discharge/inrush current tests
- New inclusion: Whisker growth test (4.41) - added to assess conductive filament growth on terminations that can affect reliability.
- Test conditions, test circuits, measurement frequencies and recovery/referee conditions are specified for consistent, repeatable evaluation.
Keywords: ESR testing, leakage current test, voltage proof, endurance test, whisker growth.
Practical applications - who uses this standard
IEC 60384-1 is used by:
- Capacitor manufacturers - to prepare sectional/detail specifications and to demonstrate product conformity.
- Component test laboratories - for standardized test plans and repeatable measurement methods.
- Design and reliability engineers - to select capacitors that meet electrical, environmental and lifetime requirements.
- Procurement and quality teams - to specify acceptance criteria and supplier verification.
- Regulatory and certification bodies - as a reference for safety and performance claims.
