IEC 60384-9-1:2005

Overview

IEC 60384-9-1:2005 is a blank detail specification published by the International Electrotechnical Commission (IEC) for fixed capacitors of ceramic dielectric, Class 2 (assessment level EZ). It is a supplementary document to the Part 9 sectional specification and defines the required style, layout and minimum content of detail specifications. Detail specifications that do not follow IEC 60384-9-1 may not be considered in accordance with IEC rules.

Key SEO phrases: IEC 60384-9-1, fixed capacitors, ceramic dielectric Class 2, blank detail specification, assessment level EZ, capacitor standard.

Key topics and requirements

• Purpose and scope
  • Establishes mandatory content and format for detail specifications used with IEC 60384-9 (Class 2 ceramic capacitors).
  • Supports consistent documentation used for component qualification, production and procurement.
• Identification elements
  • Fields to be included (organization, spec number, references to generic and sectional specifications, capacitor description, outline drawing, assessment level, reference data).
• General data
  • Recommended mounting methods, dimensions (case sizes and tolerances), ratings and characteristics (capacitance ranges, tolerance, rated voltage, climatic category, rated temperature, tangent of loss angle, insulation resistance, temperature characteristic).
• Marking and ordering
  • Mandatory marking requirements for components and packaging, and the minimum ordering information (capacitance, tolerance, rated voltage, temperature characteristic, spec reference).
• Inspection and test schedule
  • Requirements for qualification approval and lot-by-lot quality conformance inspection.
  • Test grouping (Group A, B, C), sampling plans, periodicity, severities and performance criteria (visual, dimensional, capacitance, insulation, solderability, thermal and mechanical stresses).
• Normative references
  • Cross-references necessary for correct application (e.g., IEC 60384-9 sectional specification and IEC 60410 sampling procedures).
• Governance
  • Prepared by IEC TC 40 (Capacitors and resistors for electronic equipment). Second edition, 2005.

Applications and users

Who uses IEC 60384-9-1:

• Capacitor manufacturers - to prepare detail specifications that are IEC-compliant and support component qualification.
• Quality and compliance teams - to define lot inspection, sampling and acceptance criteria.
• Procurement and suppliers - to include unambiguous ordering data and accepted test levels.
• Test laboratories and certification bodies - to run and document required inspections and conformance tests.
• Design and reliability engineers - to ensure components meet defined ratings and environmental characteristics.

Practical value: ensures consistent documentation, simplifies cross-vendor comparisons, supports supply-chain quality assurance for Class 2 ceramic capacitors.
