Fixed electric double-layer capacitors for use in electronic equipment - Part 2: Sectional specification - Electric double-layer capacitors for power application
IEC 62391-2:2025 applies to electric double-layer capacitors for power application. Electric double-layer capacitors for power are intended for applications that require discharge currents in the range from mA to A. The characteristics of the capacitors include such performance as relatively high capacitance and low internal resistance, which is applicable to Class 3 and Class 5 of the measurement classification specified in IEC 62391-1:2022. The object of this document is to specify preferred ratings and characteristics and to select from IEC 62391-1:2022 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements specified in detail specifications referring to this document provide specific test severities and requirements of an equal or higher performance level. The definition of power density and its calculating procedure can be found in Annex A. This edition includes the following significant technical changes with respect to the previous edition: a) the document has been completely restructured to comply with the ISO/IEC Directives, Part 2; b) introduction of a new technical categorization for the test methods; c) reorganization of the test methods have been according to these new categories; d) revision of the tables, figures and references according to changes.

Condensateurs électriques fixes à double couche utilisés dans les équipements électriques et électroniques - Partie 2: Spécification intermédiaire - Condensateurs électriques à double couche pour application de puissance
L’IEC 62391-2:2025 s’applique aux condensateurs électriques à double couche pour application de puissance. Les condensateurs électriques à double couche pour application de puissance sont destinés aux applications qui exigent des courants de décharge dans la gamme des milliampères aux ampères. Les caractéristiques des condensateurs incluent des performances comme une capacité relativement élevée et une faible résistance interne, ce qui concerne la classe 3 et à la classe 5 de la classification des mesures spécifiée dans l’IEC 62391-1:2022. Le présent document a pour objet de spécifier les valeurs assignées et caractéristiques préférentielles, et de choisir, à partir de l’IEC 62391-1:2022, les procédures d’assurance de la qualité, essais et méthodes de mesure appropriés, et de donner les exigences de performances générales pour ce type de condensateur. Les sévérités d’essai et les exigences stipulées dans les spécifications particulières faisant référence au présent document constituent des sévérités d’essai et des exigences spécifiques, correspondant à un niveau de performances supérieur ou égal. La définition de la densité de puissance et sa procédure de calcul peuvent être consultées à l’Annexe A. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) la structure du document a été intégralement réétudiée afin de respecter les Directives ISO/IEC, Partie 2: b) introduction d’une nouvelle classification technique pour les méthodes d’essai; c) réorganisation des méthodes d’essai selon ces nouvelles catégories; d) révision des tableaux, figures et références en fonction des modifications apportées.

70 FOREWORD
71 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
72 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
73 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
74 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
75 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
76 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
77 in the subject dealt with may participate in this preparatory work. International, governmental and non -
78 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
79 with the International Organization for Standardization (ISO) in accordance with conditions determined by
80 agreement between the two organizations.
81 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
82 consensus of opinion on the relevant subjects since each technical committee has representation from all
83 interested IEC National Committees.
84 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
85 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
86 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
87 misinterpretation by any end user.
88 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
89 transparently to the maximum extent possible in their national and regional publications. Any divergence
90 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
91 the latter.
92 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
93 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
94 services carried out by independent certification bodies.
95 6) All users should ensure that they have the latest edition of this publication.
96 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
97 members of its technical committees and IEC National Committees for any personal injury, property damage or
98 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
99 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
100 Publications.
101 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
102 indispensable for the correct application of this publication.
103 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
104 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
105 IEC 62391-2 has been prepared by IEC technical committee 40: Capacitors and resistors for
106 electronic equipment. It is an International Standard.
107 This second edition cancels and replaces the first edition published in 2006. This edition
108 constitutes a technical revision.
