IEC 60384-9:2024

Fixed capacitors for use in electronic equipment - Part 9: Sectional specification - Fixed capacitors of ceramic dielectric, Class 2

IEC 60384-9:2024 is applicable to fixed capacitors of ceramic dielectric with a defined temperature coefficient (dielectric Class 2), intended for use in electronic equipment, including leadless capacitors but excluding fixed surface mount multilayer capacitors of ceramic dielectric, which are covered by IEC 60384-22 (Class 2). Capacitors for electromagnetic interference suppression are not included, but are covered by IEC 60384-14. The object of this document is to specify preferred ratings and characteristics and to select from IEC 60384-1:2021 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. Further information on the conception of generic, sectional and detail specifications can be found in the Introduction of IEC 60384-1:2021.
This edition includes the following significant technical changes with respect to the previous edition:
a) The document has been completely restructured to comply with ISO/IEC Directives, Part 2 and to make it more useable; tables, figures and references have been revised accordingly. Annex X contains all cross-references of changes in clause/subclause numbers.
b) The requirements of reference temperature 25 °C have been added in Table 7, Table 9, Table 11, Table 13 and Table 15.
c) The table of temperature characteristics of capacitance for the reference temperature 25 °C have been added in Table B.1, Table B.2 and Table B.3.
d) Annex B has been changed from informative to normative.
e) Clause C.5 (Test schedule for quality conformance inspection) has been newly added to withdraw the blank detail specification: IEC 60384-9-1.

Condensateurs fixes utilisés dans les équipements électroniques - Partie 9: Spécification intermédiaire - Condensateurs fixes à diélectrique en céramique, Classe 2

L’IEC 60384-9:2024 s’applique aux condensateurs fixes à diélectriques en céramique avec un coefficient de température défini (classe diélectrique 2), destinés à être utilisés dans les équipements électroniques, y compris les condensateurs sans plomb, à l’exclusion des condensateurs multicouches fixes à diélectriques en céramique pour montage en surface, qui sont couverts par l’IEC 60384-22 (classe 2). Les condensateurs d’antiparasitage ne sont pas inclus, mais sont couverts par l’IEC 60384-14. Le présent document a pour objet de spécifier les valeurs assignées et caractéristiques préférentielles, de sélectionner les procédures d’assurance de la qualité appropriées, les essais et les méthodes de mesure en se référant à l’IEC 60384-1:2021 et de fournir des exigences de performances générales pour ce type de condensateur. Les sévérités et les exigences des essais stipulées dans les spécifications particulières se référant au présent document fournissent des sévérités et des exigences d’essai d’un niveau de performance supérieur ou égal. Des informations supplémentaires sur la conception des spécifications génériques, intermédiaires et particulières sont données dans l’introduction de l’IEC 60384-1:2021.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) le document a été entièrement restructuré pour se conformer aux Directives ISO/IEC, Partie 2, et pour en faciliter l’utilisation; les tableaux, les figures et les références ont été révisés en conséquence. L’Annexe X donne les références croisées des modifications apportées par rapport à la version précédente, avec numéros d’article/de paragraphe correspondants;
b) les exigences relatives à la température de référence de 25 °C ont été ajoutées dans le Tableau 7, le Tableau 9, le Tableau 11, le Tableau 13 et le Tableau 15;
c) les caractéristiques de température pour la capacité, à la température de référence de 25 °C, ont été ajoutées dans le Tableau B.1, le Tableau B.2 et le Tableau B.3;
d) l’Annexe B est passée d’informative à normative;
e) l’Article C.5 (Programme d’essais pour le contrôle de conformité de la qualité) a été ajouté afin de pouvoir retirer la spécification particulière-cadre: IEC 60384-9-1.
