IEC 60384-18-2:2007

Overview

IEC 60384-18-2:2007 is an international standard issued by the International Electrotechnical Commission (IEC) which provides a blank detail specification for fixed aluminium electrolytic surface mount capacitors with non-solid electrolyte, assessment level EZ. This standard is intended for use as a template in the preparation and evaluation of detail specifications, complementing the broader sectional specification IEC 60384-18.

The document defines the style, layout, and minimum required content that manufacturers and specification writers must adhere to when documenting the characteristics, testing, and quality conformance procedures for this class of capacitors. Detail specifications that do not comply may not be recognized as conforming to IEC norms, ensuring uniformity and traceability in the electronic components sector.

Key Topics

The standard addresses critical considerations for creating comprehensive detail specifications for fixed aluminium electrolytic surface mount capacitors with non-solid electrolyte. Key topics include:

• Document Structure: Specification of layout, required sections, and minimum content for detail specifications.
• Capacitor Identification: Guidance on item description, construction information, and standardized outline drawings for compatibility and interchangeability.
• Ratings and Characteristics: Requirements for declaring capacitance range, tolerance, rated and category voltages, temperature ratings, ripple current handling, loss angle, leakage current, and impedance.
• Testing and Inspection: Standardized test schedules and procedures for qualification and quality conformance, covering aspects such as visual inspection, dimensional checks, electrical performance, and environmental resistance.
• Marking and Ordering Information: Instructions for product labeling and the minimum information required for orders, ensuring clear communication between suppliers and customers.
• Quality Documentation: Requirements for records of released lots, inspection methods, and additional/severe testing when needed to meet application-specific needs.

Applications

IEC 60384-18-2:2007 is highly valuable in numerous applications where the reliability and performance of surface mount electrolytic capacitors are critical:

• Specification Development: Assists manufacturers and engineers in preparing detail specifications that ensure product consistency and compatibility with IEC international standards.
• Quality Assurance: Provides a recognized benchmark for assessing product conformity during procurement, production, and inspection audits within the electronics manufacturing industry.
• Component Sourcing: Facilitates the standardized identification and ordering of aluminium electrolytic capacitors for use in a variety of electronic assemblies, including consumer electronics, automotive electronics, industrial controls, and telecommunications.
• Product Qualification: Outlines conformance procedures for type testing, lot release, and ongoing reliability assessments, ensuring components meet required performance levels in end-use conditions.

Related Standards

For comprehensive understanding and compliance in the field of fixed capacitors for electronic equipment, the following standards are closely related and frequently referenced:

• IEC 60384-1: Fixed capacitors for use in electronic equipment - Part 1: Generic specification. The foundational document for fixed capacitor standards.
• IEC 60384-18: Sectional specification focusing on aluminium electrolytic surface mount capacitors, covering both solid and non-solid electrolyte types.
• IEC 60410: Sampling plans and procedures for inspection by attributes, relevant to quality conformance inspection under IEC 60384-18-2.

By adhering to IEC 60384-18-2:2007, organizations support robust product documentation and international harmonization in the specification, testing, and supply of surface mount aluminium electrolytic capacitors. This not only streamlines the product development lifecycle but also strengthens supply chain integrity and facilitates global market access.
