Fixed capacitors for use in electronic equipment - Part 21: Sectional specification - Fixed surface mount multilayer capacitors of ceramic dielectric, Class 1 (IEC 60384-21:2019)

This part of IEC 60384 is applicable to fixed unencapsulated surface mount multilayer
capacitors of ceramic dielectric, Class 1, 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 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 are of equal or higher performance levels; lower performance levels are not
permitted.

Les exigences et les sévérités des essais prescrits dans les spécifications particulières se référant à la présente spécification intermédiaire sont d'un niveau de performance supérieur ou égal, des niveaux de performance inférieurs ne sont pas admis. La présente 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 pour l'harmonisation avec l'IEC 60384-22; - suppression de la description de la puissance réactive admissible en 6.2.2, parce qu'elle n'est pas adaptée aux besoins du présent document; - les dimensions de 0201M à l'Annexe A ont été ajoutées.

Fiksni kondenzatorji za uporabo v elektronski opremi - 21. del: Področna specifikacija - Fiksni večplastni kondenzatorji za površinsko namestitev s keramičnim dielektrikom, razred 1 (IEC 60384-21:2019)

Ta del standarda IEC 60384 se uporablja za fiksne nezaprte večplastne kondenzatorje za površinsko namestitev s keramičnim dielektrikom razreda 1 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 predpisati prednostne vrednosti in lastnosti, izbrati primerne postopke za ovrednotenje kakovosti, preskuse in merilne metode iz standarda IEC 60384-1 ter podati splošne zahteve glede zmogljivosti za ta tip kondenzatorja. Preskusne stopnje in zahteve, predpisane v podrobnih specifikacijah, ki se navezujejo na to področno specifikacijo, so enake ali višje ravni učinkovitosti; nižje ravni niso dovoljene.

Part 21: Sectional specification –
Fixed surface mount multilayer capacitors
of ceramic dielectric, Class 1

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60384-21 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

a) revision of the structure in accordance with ISO/IEC Directives, Part 2:2016 to the extent practicable, and for harmonizing with IEC 60384-22; b) deletion of the description on the permissible reactive power in 6.2.2 because it is not appropriate for the purposes of this document; SIST EN IEC 60384-21:2019
