25、ation Fixed tantalum electrolytic surface mount capacitors with conductive polymer solid electrolyte FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The obje
26、ct 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 Specificatio
27、ns (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 liaisi
28、ng 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,
29、 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
30、 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 Co
31、mmittees 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 pr
32、ovide 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 l
33、atest 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, w
34、hether 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
35、 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
36、60384-24 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This second edition cancels and replaces the first edition published in 2006 and constitutes a technical revision. This edition includes the following significant technical changes with respe
37、ct to the previous edition: Revision of the structure in accordance with ISO/IEC Directives, Part 2:2011 (sixth edition) to the extent practicable, and harmonization between other similar kinds of documents. In addition, Clause 0 and all the tables have been reviewed in order to prevent duplications
38、 and contradictions. v The text of this standard is based on the following documents: FDIS Report on voting 40/2382/FDIS 40/2395/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted i
39、n accordance with the ISO/IEC Directives, Part 2. The list of all parts of the IEC 60384 series, under the general title Fixed capacitors for use in electronic equipment, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the
40、stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.EIA-60384-24 Page 1 FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT Part
41、 24: Sectional specification Fixed tantalum electrolytic surface mount capacitors with conductive polymer solid electrolyte 1 General 1.1 Scope This part of IEC 60384 applies to fixed tantalum electrolytic surface mount capacitors with conductive polymer solid electrolyte primarily intended for d.c.
42、 applications for use in electronic equipment. Fixed tantalum electrolytic surface mount capacitors with solid (MnO2) electrolyte are not included but are covered by IEC 60384-3. These capacitors are primarily intended for use in electronic equipment to be mounted directly on substrates for hybrid c
43、ircuits or to printed boards. Capacitors for special-purpose applications may need additional requirements. 1.2 Object The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC 60384-1 the appropriate quality assessment procedures, tests and measuring m
44、ethods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted. 1.3 Normat
45、ive references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) a
