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