IEC 60384-17:2019 applies to fixed capacitors with metallized electrodes and polypropylene dielectric for use in electronic equipment. Capacitors that have mixed film and metallized electrodes are also within the scope of this standard. These capacitors may have "self-healing" properties depending on conditions of use. Capacitors covered by this specification are mainly intended for use with alternating voltage and/or for pulse applications. The maximum reactive power applicable is 10 000 var and the maximum peak voltage is 3 000 V. This edition includes the following significant technical changes with respect to the previous edition:
a) all parts of the document have been revised based on the ISO/IEC Directives, Part 2:2016 (seventh edition) and harmonization between other similar kinds of documents;
b) tables and Clause 4 have been revised so as to prevent duplications and contradictions;
c) new damp heat steady-state robustness classes with test conditions have been added in text, in Clause 4 and in Annex A.
