EN IEC 60384-21:2024

Fixed capacitors for use in electronic equipment - Part 21: Sectional specification - Fixed surface mount multilayer capacitors of ceramic dielectric, Class 1

IEC 60384-21:2024 is applicable to fixed unencapsulated surface mount multilayer capacitors of ceramic dielectric with a defined temperature coefficient (dielectric Class 1), intended 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revised accordingly; Annex X contains all cross-references of changes in clause/subclause numbers; b) the terms have been replaced by the letter symbols in Table 3; c) code of temperature coefficient and tolerance of C0G, U2J have been added in Table 4, Table 6, Table 8, Table 9, Table 11, Table 13, Table 16 and Annex B; d) the requirement in 5.5.2(visual examination) has been repeated in 5.9.3, 5.10.5, 5.11.4, 5.11.4, 5.13.7, 5.14.5 and 5.15.5; e) the deflection D in the very robust designs has been added in 5.9.1; f) Annex B has been changed informative into normative; g) Clause C.5 (Test schedule for quality conformance inspection) has been newly added to withdraw the blank detail specification: IEC 60384-21-1.

Festkondensatoren zur Verwendung in Geräten der Elektronik - Teil 21: Rahmenspezifikation - Oberflächenmontierbare Vielschichtkeramik-Festkondensatoren, Klasse 1

Condensateurs fixes utilisés dans les équipements électroniques - Partie 21: Spécification intermédiaire - Condensateurs multicouches fixes à diélectriques en céramique pour montage en surface, de Classe 1

L’IEC 60384-21:2024 s’applique aux condensateurs multicouches fixes à diélectriques en céramique pour montage en surface non encapsulés, avec un coefficient de température défini (diélectrique de Classe 1), destinés à être 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 termes ont été remplacés par des symboles littéraux dans le Tableau 3; c) le codage de coefficient de température et tolérance de C0G et U2J a été ajouté dans le Tableau 4, le Tableau 6, le Tableau 8, le Tableau 9, le Tableau 11, le Tableau 13, le Tableau 16 et à l’Annexe B; d) l’exigence de 5.5.2 (examen visuel) a été répétée en 5.9.3, en 5.10.5, en 5.11.4, en 5.11.4, en 5.13.7, en 5.14.5 et en 5.15.5; e) la flèche D dans les modèles très robustes a été ajoutée en 5.9.1; f) l’Annexe B est passée d’informative à normative; g) l’Article C.5 (Programme d’essais pour le contrôle de conformité de la qualité) a été ajouté pour retirer la spécification particulière-cadre: IEC 60384-21-1.

Fiksni kondenzatorji za uporabo v elektronski opremi - 21. del: Področna specifikacija - Fiksni večplastni kondenzatorji za površinsko namestitev s keramičnim dielektrikom, razred 1 (IEC 60384-21:2024)

Standard IEC 60384-21:2024 se uporablja za fiksne nezaprte večplastne kondenzatorje za površinsko namestitev s keramičnim dielektrikom z določenim temperaturnim koeficientom (dielektrik razreda 1), namenjene za uporabo v elektronski opremi. Ti kondenzatorji imajo metalizirane priključne blazinice ali varilne trakove ter so namenjeni namestitvi na tiskana vezja ali neposredno na podlage za hibridne tokokroge. Kondenzatorji za preprečevanje elektromagnetnih motenj niso vključeni, vendar so zajeti v standardu IEC 60384-14. Cilj tega dokumenta je določiti prednostne vrednosti in lastnosti, izbrati primerne postopke za ovrednotenje kakovosti, preskuse in merilne metode iz standarda IEC 60384-1:2021 ter podati splošne zahteve glede zmogljivosti za ta tip kondenzatorja. Preskusne stopnje in zahteve, določene v podrobnih specifikacijah, ki se navezujejo na to področno specifikacijo, so na enaki ali višji ravni zmogljivosti. Več informacij o oblikovanju splošnih, področnih in podrobnih specifikacij je na voljo v uvodu standarda IEC 60384-1:2021.
Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) dokument je bil v celoti preoblikovan tako, da je skladen z 2. delom direktiv ISO/IEC in je njegova vsebina uporabnejša; preglednice, slike in sklici so bili ustrezno pregledani; dodatek X vsebuje vsa navzkrižna sklicevanja na spremembe številk točk/podtočk;
b) izrazi v preglednici 3 so bili zamenjani s črkovnimi oznakami;
c) v preglednicah 4, 6, 8, 9, 11, 13 in 16 ter v dodatku B sta bili dodani oznaki za temperaturni koeficient in toleranco (C0G, U2J);
d) zahteva iz točke 5.5.2 (vizualni pregled) je bila ponovljena v točkah 5.9.3, 5.10.5, 5.11.4, 5.11.4, 5.13.7, 5.14.5 in 5.15.5;
e) v točki 5.9.1 je bil dodan odklon (D) pri zelo robustnih izvedbah;
f) dodatek B je bil spremenjen iz informativnega v normativni;
g) dodana je bila nova točka C.5 (Razpored preskusov za prevzemno kontrolo), ki je nadomestila okvirno podrobno specifikacijo: IEC 60384-21-1.
