Overview
IEC 60384-25-1:2006 is the IEC blank detail specification for surface mount fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte (assessment level EZ). Published as the first edition in June 2006, this document is a supplementary specification to the sectional specification (IEC 60384-25) and the generic spec (IEC 60384-1). Its primary purpose is to define the required style, layout and minimum content of manufacturer or national detail specifications. Detail specifications that do not comply with IEC 60384-25-1:2006 should not be described as being in accordance with IEC.
Key Topics and Requirements
- Identification fields and format: predefined placeholders ([1]–[9]) for authority, specification numbers, capacitor description, outline drawing, assessment level (EZ), and reference data to ensure consistent presentation.
- General data: recommended mounting methods, case size references and maximum/nominal dimensions (L, W, H), and outline drawings for interchangeability.
- Ratings and characteristics: required declaration of rated capacitance range, capacitance tolerance, rated and surge voltages, climatic category, rated temperature, rated ripple current, tangent of loss angle (tan δ), leakage current and equivalent series resistance (ESR).
- Tables and numeric requirements: templates for case-size vs. capacitance/voltage (Table 2), ripple/ESR/tan δ/leakage (Table 3), and soldering/temperature resistance limits (Table 4). Test conditions cited include frequencies such as 120 Hz and 100 kHz, temperatures like 20 °C, and high-temperature reference points (e.g., 105 °C or 125 °C).
- Marking & ordering information: mandatory marking rules and minimum order data (capacitance, tolerance, voltage, detail spec reference, packaging).
- Inspection & test schedule: qualification approval procedures and quality conformance inspection schedules (Table 6) covering visual, solderability, soldering-heat resistance, leakage, capacitance, ESR, tan δ and other performance checks. Example: leakage current measurement may use a protective resistor: 1 000 Ω.
- Normative references: specifically references IEC 60384-1 and IEC 60384-25.
Applications and Who Uses This Standard
IEC 60384-25-1 is intended for:
- Capacitor manufacturers preparing national or product-specific detail specifications in a format consistent with IEC requirements.
- OEMs and electronic designers who require consistent specification documents for component selection and interchangeability.
- Quality assurance and test laboratories implementing qualification and lot-by-lot conformance testing.
- Procurement and compliance teams ensuring vendor detail specifications meet IEC formatting and minimum content before acceptance.
Practical benefits include streamlined supplier documentation, clearer inspection criteria, and improved interoperability of surface mount aluminium electrolytic capacitors with conductive polymer solid electrolyte across global supply chains.
