Overview
IEC 60384-22-1:2004 is a blank detail specification published by the IEC for fixed surface-mount multilayer capacitors (SMD MLCC) of ceramic dielectric, Class 2 - Assessment level EZ. It is a supplementary document to the sectional specification (IEC 60384-22) that prescribes the required style, layout and minimum content for detail specifications. Detail specifications that do not follow these requirements may not be considered in accordance with IEC practice. This edition includes the September 2004 corrigendum.
Key topics and requirements
The standard defines the mandatory structure and the technical items that a manufacturer’s detail specification must contain, including:
- General data
- Recommended mounting methods, outline drawings and case size references
- Ratings and characteristics: rated capacitance range, tolerance, rated and category voltages, climatic and temperature categories, tan δ, insulation resistance
- Marking and ordering information (minimum order details such as capacitance, tolerance, rated DC voltage, temperature characteristic and detail-spec reference)
- Normative references
- Includes references such as IEC 60384-1 (generic capacitor spec), IEC 60384-22 (sectional spec for SMD MLCC Class 2) and IEC 60410 (sampling and inspection)
- Inspection and test requirements
- Quality conformance and qualification procedures, sampling plans and test schedule tables
- Tests cited: capacitance, tangent of loss angle (tan δ), insulation resistance, voltage proof, solderability, temperature characteristics, resistance to soldering heat, robustness of termination, substrate bending, solvent resistance, ESR/impedance when required
- Tables for case sizes, capacitance/voltage values, other characteristics and lot-by-lot or periodic test schedules
Applications
This blank detail specification is used to:
- Standardize the content and presentation of manufacturer detail specifications for SMD MLCC Class 2 components
- Ensure consistent documentation for procurement, quality control, and component qualification
- Serve as the authoritative template when drafting national or supplier detail specifications that must conform to IEC practices
Who uses this standard
- Capacitor manufacturers and design engineers preparing or reviewing detail specifications
- Quality assurance and test laboratories performing qualification and lot conformance inspection
- Purchasing engineers and OEMs who require IEC-compliant component documentation
- Standards committees and national bodies adopting or referencing IEC detail specifications
