IEC 60384-13:2011

Overview

IEC 60384-13:2011 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for fixed direct current (d.c.) capacitors using polypropylene film dielectric with metal foil electrodes. These capacitors are designed specifically for use in electronic equipment, ensuring reliable performance in various applications. This fourth edition replaces the previous 2006 version and incorporates updated testing and assessment procedures to maintain quality and reliability.

The standard excludes capacitors intended for electromagnetic interference (EMI) suppression, which are covered under IEC 60384-14. IEC 60384-13:2011 focuses on the preferred ratings, characteristics, and quality assessment protocols for polypropylene film dielectric metal foil capacitors used in DC circuits.

Key Topics
