IEC 60384-25:2015 applies to fixed aluminium electrolytic surface mount capacitors with conductive polymer solid electrolyte, primarily intended for d.c. applications for use in electronic equipment. These capacitors are primarily intended for use in electronic equipment to be mounted directly on substrates for hybrid circuits or to printed boards. This edition includes the following significant technical changes with respect to the previous edition: a) Revision of the structure in accordance with ISO/IEC Directives, Part 2:2011 (sixth edition) to the extent practicable, and harmonization between other similar kinds of documents. b) In addition, Clause 4 and all the tables have been reviewed in order to prevent duplications and contradictions.
