IEC 60384-17:2019

Overview

IEC 60384-17:2019 is an international standard established by the International Electrotechnical Commission (IEC) for fixed capacitors with metallized polypropylene film dielectric intended for use in electronic equipment. The standard specifically covers capacitors with metallized electrodes or a combination of metallized and foil film electrodes. These capacitors can exhibit self-healing properties and are primarily intended for alternating current (AC) voltage and pulse applications where reliable performance under specified electrical and environmental conditions is critical.

IEC 60384-17:2019 details the performance grades, quality assessment, ratings, and standardized test procedures for such capacitors. The maximum reactive power handled by these capacitors is up to 10,000 var, and the maximum peak voltage is up to 3,000 V. This edition incorporates harmonized terminology, revised tables and requirements, and added humidity robustness classes, ensuring broader applicability and alignment with other international standards.

Key Topics

IEC 60384-17:2019 addresses a wide range of topics related to the construction, performance, and testing of fixed metallized polypropylene film capacitors, including:

• Scope and Purpose: Specifies requirements for capacitors using metallized polypropylene film dielectric used in electronic equipment for AC and pulse applications.
• Performance Grades: Defines two grades - Grade 1 for long-life, stringent applications, and Grade 2 for general use.
• Ratings and Characteristics:
  • Maximum reactive power: 10,000 var
  • Maximum peak voltage: 3,000 V
  • Preferred ratings and climatic categories
• Quality Assessment Procedures: Outlines qualification, inspection, and quality control measures to ensure product consistency.
• Testing and Measurement:
  • Capacitance, voltage proof, loss angle, insulation resistance
  • Mechanical tests (vibration, shock, soldering heat, etc.)
  • Environmental resistance (rapid temperature changes, damp heat, humidity robustness)
• Marking and Identification: Requirements for clear marking on capacitors and packaging (capacitance, voltage, manufacturer, date code, climatic category, and more).
• Detail Specification Guidance: Includes requirements for specifying dimensions, mounting, and application-specific characteristics.

Applications

Fixed metallized polypropylene film dielectric capacitors compliant with IEC 60384-17:2019 are widely used in the following applications:

• AC and Pulse Circuits: Ideal for circuits demanding high stability and long life under alternating voltage conditions and repetitive pulse loads.
• Power Electronics: Used in filtering, coupling, and decoupling within power supplies, inverters, and converters.
• Industrial Control Systems: Suitable for demanding conditions and frequent switching environments.
• Consumer and Professional Electronic Equipment: Ensures consistent performance in audio, video, and data processing systems.
• Lighting and Motor Applications: When reactive power and peak voltage limits match the specification.
• Applications Requiring High Humidity Robustness: The added robustness classes make these capacitors suitable for environments with high humidity and temperature fluctuations.

Note: Capacitors for electromagnetic interference suppression, electrical shock protection, or specialized lighting/motor circuits are covered by other IEC standards and are excluded from IEC 60384-17's scope.
