METHOD FOR THE DETERMINATION OF THE SPACE
REQUIRED BY CAPACITORS AND RESISTORS
WITH UNIDIRECTIONAL TERMINATIONS

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 60717 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 1981, and constitutes
a technical revision.
The main technical changes with respect to the first edition are the following:
• employment of the millimetre-based grid, the preferred grid system given in IEC 60097,
• employment of SI units only, causing deletion of the imperial dimensions from Table 1,
• reduction of the tolerance on the chamfer depth in Figure 1, and
• introduction of requirements on information to be given in a relevant specification.

The text of this standard is based on the following documents:
CDV Report on voting
40/2108/CDV 40/2123/RVC
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 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site 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.

METHOD FOR THE DETERMINATION OF THE SPACE
REQUIRED BY CAPACITORS AND RESISTORS
WITH UNIDIRECTIONAL TERMINATIONS

1 Scope
This International Standard applies to capacitors and resistors with unidirectional wire
terminations intended for use in electronic equipment.
This standard provides a method for determination of the space required by capacitors and
resistors with unidirectional wire terminations.
NOTE Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the
maximum space for which it is designed. This may be achieved by means of fixed gauges.
2 Normative 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) applies.
IEC 60097, Grid systems for printed circuits
IEC 60294:–, Measurement of the dimensions of a cylindrical component having two axial
terminations
IEC 60301, Preferred diameters of wire terminations of capacitors and resistors
3 Gauge board
The gauge board shall provide an orthogonal matrix of holes based on standard grid
dimensions as given in IEC 60097. Unless prescribed otherwise by the relevant specification,
the nominal grid spacing shall be a multiple of 0,5 mm, preferably 2,5 mm. The non-
cumulative tolerance on the relative position of grid holes along the same axis shall be
±0,02 mm.
The gauge board shall have a nominal thickness T of 1,5 mm.
The grid hole diameters shall relate to the dimensions of the wire terminations according to
commonly accepted printed circuit board practice. Unless prescribed otherwise by the
relevant specification, the diameter of grid holes in the gauge board shall be selected from
Table 1.
