Fixed capacitors for use in electronic equipment - Part 26: Sectional specification - Fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte

IEC 60384-26:2018 is now available as IEC 60384-26:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60384-26:2018 applies to fixed aluminium electrolytic capacitors with conductive polymer solid electrolyte primarily intended for d.c. applications for use in electronic equipment. Fixed aluminium electrolytic capacitors with solid (MnO2) electrolyte are covered by IEC 60384-4. Fixed aluminium electrolytic surface mount capacitors with conductive polymer solid electrolyte are covered by IEC 60384-25. The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted. This edition includes the following significant technical changes with respect to the previous edition:
- revision of the structure in accordance with ISO/IEC Directives, Part 2:2016 to the extent practicable, and harmonization between other similar kinds of documents;
- in addition, Clause 4 and all the tables have been reviewed in order to prevent duplications and contradictions.
The contents of the corrigendum of April 2020 have been included in this copy.

Condensateurs fixes utilisés dans les équipements électroniques - Partie 26: Spécification intermédiaire - Condensateurs fixes électrolytiques en aluminium à électrolyte solide en polymère conducteur

IEC 60384-26:2018 est disponible sous forme de IEC 60384-26:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 60384-26:2018 s’applique aux condensateurs fixes électrolytiques en aluminium à électrolyte solide en polymère conducteur destinés principalement aux applications en courant continu dans des équipements électroniques. Les condensateurs fixes électrolytiques en aluminium à électrolyte solide (MnO2) sont couverts par l'IEC 60384-4. Les condensateurs fixes électrolytiques en aluminium pour montage en surface à électrolyte solide en polymère conducteur sont couverts par l'IEC 60384-25. Le présent document a pour objet de prescrire des caractéristiques et des valeurs assignées préférentielles et de sélectionner en se référant à l'IEC 60384-1, les procédures d’assurance de la qualité appropriées, les essais et les méthodes de mesure et de donner les exigences de performances générales pour ce type de condensateur. Les sévérités et les exigences d'essai prescrites dans les spécifications particulières se rapportant à la présente spécification intermédiaire doivent présenter des niveaux de performances supérieurs ou égaux, parce que des niveaux de performance inférieurs ne sont pas autorisés. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- révision de la structure conformément aux directives ISO/IEC, Partie 2:2016, dans la mesure du possible, et harmonisation avec d'autres types de documents similaires;
- en outre, l'Article 4 et tous les tableaux ont été révisés dans le but d'éviter les répétitions et les contradictions.
Le contenu du corrigendum d'avril 2020 a été pris en considération dans cet exemplaire.

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 26: Sectional specification – Fixed aluminium electrolytic
capacitors with conductive polymer solid electrolyte
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60384-26 has been prepared by IEC technical committee 40:

Capacitors and resistors for electronic equipment.

This second edition cancels and replaces the first edition published in 2010. This edition

constitutes a technical revision.

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 2:2016 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.

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of the IEC 60384 series can be found, under the general title Fixed

capacitors for use in electronic equipment, on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
