Overview
IEC 60384-16:2019 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the requirements for fixed metallized polypropylene film dielectric DC capacitors used in electronic equipment. These capacitors feature metallized electrodes and a polypropylene dielectric, providing reliability and stability primarily in direct voltage (DC) applications. With potential self-healing properties, these capacitors are designed to maintain performance and safety under specific operational conditions.
This standard excludes capacitors intended for alternating current (AC) or pulse applications, which are covered by IEC 60384-17, as well as capacitors for electromagnetic interference (EMI) suppression (IEC 60384-14), electrical shock protection (IEC 60065), fluorescent lamp, and motor capacitors.
