FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60384-4-1 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 1985, amendment 1
(1992) and amendment 2 (1996). This second edition constitutes a technical revision.
The text of this standard is based on the first edition, amendment 1, amendment 2 and the

following documents:
FDIS Report on voting
40/1123/FDIS 40/1169/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 in accordance with the ISO/IEC Directives, Part 3.
The QC number that appears on the front cover of this publication is the specification number
of the IEC Quality Assessment System for Electronic Components (IECQ).

60384-4-1  IEC:2000(E) – 3 –
The committee has decided that the contents of this publication will remain unchanged until
2003. At this date, the publication will be

• reconfirmed;
• withdrawn;
• replaced by a revised edition; or

• amended.
A bilingual version of this standard may be issued at a later date.

Part 4: Blank detail specification –

Aluminium electrolytic capacitors with non-solid electrolyte –

Assessment level E
Blank detail specification
A blank detail specification is a supplementary document to the sectional specification and
contains requirements for style and layout and minimum content of detail specifications. Detail
specifications not complying with these requirements may not be considered as being in
accordance with IEC specifications nor shall they be so described.
In the preparation of detail specifications, the contents of 1.4 of the sectional specification
shall be taken into account.
The numbers between brackets on the first page correspond to the following information
which shall be inserted in the position indicated.
Identification of the detail specification
[1] The International Electrotechnical Commission or the National Standards Organization
under whose authority the detail specification is drafted.
[2] The IEC or National Standards number of the detail specification, data of issue and any
further information required by the national system.
[3] The number and issue number of the IEC or national generic specification.
[4] The IEC number of the blank detail specification.
Identification of the capacitor
[5] A short description of the type of capacitor.
[6] Information on typical construction (when applicable).
NOTE When the capacitor is not designed for use in printed board applications, this is clearly stated in the
detail specification in this position.

[7] Outline drawing with main dimensions which are of importance for interchangeability
and/or reference to the national or international documents for outlines. Alternatively, this
drawing may be given in an annex to the detail specification.
[8] Application or group of applications covered and/or assessment level.
NOTE The assessment level(s) to be used in a detail specification are selected from 3.5.4 of the sectional
specification. This implies that one blank detail specification may be used in combination with several
assessment levels, provided the grouping of the tests does not change.
[9] Reference data on the most important properties, to allow comparison between the
various capacitor types.
