Overview
IEC 60384-4-1:2007 is a blank detail specification published by the International Electrotechnical Commission (IEC) for fixed aluminium electrolytic capacitors with non-solid electrolyte (assessment level EZ). This document is a supplementary template to the sectional specification (IEC 60384-4) and defines the required style, layout and minimum content of individual detail specifications. Detail specifications that do not follow this blank template are not to be described as being in accordance with IEC specifications. The 2007 third edition contains minor revisions to tables, figures and references and corresponds to the English version (bilingual published 2008).
Key topics and requirements
- Purpose: Defines the mandatory structure and content for detail specifications used to describe fixed aluminium electrolytic capacitors (non-solid).
- Identification fields: Instructions on how to insert authority, document numbers, outline drawings, assessment level (EZ), and reference data.
- General data: Required entries for mounting methods, dimensions, ratings and characteristics such as capacitance range, tolerance, rated voltage, category voltage, climatic category, rated temperature, ripple current, leakage current, tangent of loss angle (or ESR as an alternative), impedance and reverse voltage (if applicable).
- Tables and figures: Prescribed tables for case size/dimensions, capacitance vs. case size, loss tangent/impedance/ripple current, and other characteristics.
- Marking and ordering: Mandatory marking requirements and minimum ordering information (capacitance, tolerance, rated DC voltage, detail specification reference).
- Inspection and quality conformance: Requirements for qualification approval and lot-by-lot inspection; references sampling procedures to IEC 60410 and includes a test schedule (Table 5) covering visual, electrical (leakage, capacitance, tan δ/ESR, impedance), solderability, high-temperature storage and recovery tests.
- Traceability and records: Options for certified records of released lots and additional information fields.
Applications and users
IEC 60384-4-1:2007 is intended for:
- Capacitor manufacturers preparing IEC-conforming detail specifications for aluminium electrolytic capacitors (non-solid).
- Quality, compliance and test laboratories performing qualification and lot conformance inspections using the prescribed tables and sampling plans.
- Purchasing/procurement teams and OEMs who require IEC-compliant component specifications for reliable sourcing and interchangeability.
- Design and reliability engineers who need standardized parameter definitions (tan δ vs ESR, ripple current, leakage) for component selection.
- Standards writers and national committees using the blank template to produce national or vendor-specific detail specifications while maintaining IEC alignment.
