(Main)Fixed capacitors for use in electronic equipment - Part 22: Sectional specification - Fixed surface mount multilayer capacitors of ceramic dielectric, Class 2
Fixed capacitors for use in electronic equipment - Part 22: Sectional specification - Fixed surface mount multilayer capacitors of ceramic dielectric, Class 2
IEC 60384-22:2024 is applicable to fixed unencapsulated surface mount multilayer capacitors of ceramic dielectric, Class 2, for use in electronic equipment. These capacitors have metallized connecting pads or soldering strips and are intended to be mounted on printed boards, or directly onto substrates for hybrid circuits.
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 sectional specification 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 the ISO/IEC Directives, Part 2 and to make it more useable; tables, figures and references have been revised accordingly.
b) The requirements of reference temperature 25 °C has been added in Table 5, Table 9, Table 10, Table 12, Table 14 and Table 17.
c) The table of temperature characteristics of capacitance for the reference temperature 25 °C have been added in Table C.1, Table C.2 and Table C.3.
d) The requirement in 5.5.2 (visual examination) has been repeated in 5.9.3, 5.10.6, 5.11.4, 5.12.6, 5.13.8, 5.14.6 and 5.15.6.
e) The deflection D in the very robust designs has been added in 5.9.1.
f) Annex C has been changed informative into normative.
g) Clause D.5 (Test schedule for quality conformance inspection) has been newly added to withdraw the blank detail specification: IEC 60384-22-1.
Condensateurs fixes utilisés dans les équipements électroniques - Partie 22: Spécification intermédiaire - Condensateurs multicouches fixes à diélectriques en céramique pour montage en surface, de Classe 2
L'IEC 60384-22:2024 est applicable aux condensateurs multicouches fixes à diélectriques en céramique pour montage en surface non encapsulés, Classe 2, utilisés dans les équipements électroniques. Ces condensateurs possèdent des pastilles de connexion métallisées ou des bandes de brasure et sont destinés à être montés sur des cartes imprimées ou directement sur des substrats de circuits hybrides. 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, en se référant à l’IEC 60384-1:2021, les procédures d’assurance 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 des essais spécifiées 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. Pour plus d’informations sur la conception des spécifications génériques, intermédiaires et particulières, voir 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 comporte toutes les références croisées des changements de numérotation des articles/paragraphes;
b) les exigences relatives à la température de référence de 25 °C ont été ajoutées dans le Tableau 5, le Tableau 9, le Tableau 10, le Tableau 12, le Tableau 14 et le Tableau 17;
c) le tableau des caractéristiques de température de la capacité pour la température de référence de 25 °C a été ajouté dans le Tableau C.1, le Tableau C.2 et le Tableau C.3;
d) l’exigence de 5.5.2 (examen visuel) a été répétée en 5.9.3, en 5.10.6, en 5.11.4, en 5.12.6, en 5.13.8, en 5.14.6 et en 5.15.6;
e) la flèche D dans les modèles très robustes a été ajoutée en 5.9.1;
f) l’Annexe C est passée d’informative à normative;
g) l’Article D.5 (Programme d’essais pour le contrôle de conformité de la qualité) a été ajouté pour retirer la spécification particulière-cadre: IEC 60384-22-1.
