FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 24: Sectional specification – 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 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 60384-24 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 2015. 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 2:2018, to the extent

practicable, and harmonization between other similar kinds of documents.

b) In addition, Clause 5 and all the tables have been reviewed in order to prevent

duplications and contradictions.

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 24: Sectional specification – Fixed tantalum electrolytic surface
mount capacitors with conductive polymer solid electrolyte
1 Scope

This part of IEC 60384 applies to fixed tantalum electrolytic surface mount capacitors with

conductive polymer solid electrolyte, which are primarily intended for DC applications for use

in electronic equipment.

Fixed tantalum electrolytic surface mount capacitors with solid (MnO ) 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 circuits or to printed boards.
Capacitors for special-purpose applications can need additional requirements.

The object of this document is to prescribe preferred ratings and characteristics and to select

from IEC 60384-1:2016 the appropriate quality assessment procedures, tests and measuring

methods and to give general performance requirements for this type of capacitor.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their

content constitutes requirements of this document. For dated references, only the edition

cited applies. For undated references, the latest edition of the referenced document (including

any amendments) applies.
