MARKING CODES FOR RESISTORS AND CAPACITORS

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 60062 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This sixth edition cancels and replaces the fifth edition published in 2004 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
-3
• introduction of the new code colour pink for the coding of the multiplier 10 ;
• introduction of new subclauses, 3.2 Prescription of code colours, 3.3 Methods for marking
resistance value and tolerance, 3.4 Methods for TCR marking, for improved clarity, the
subjects of colour assignment, coding of R value and tolerance, and coding of TCR is
dealt with in separate clauses;
• inclusion of illustrations for TCR marking by interrupted colour band;
• inclusion of a new subclause on a fixed length code marking, fixed length code marking of
resistance values with up to 3 significant digits, hence a fixed code length of 4 digits, and

fixed length code marking of capacitance values with up to 2 significant digits, hence a
fixed code length of 3 digits;
• introduction of two new clauses, Clause 6, Coding of properties specific to capacitors and
Clause 7, Coding of properties specific to resistors;
• introduction of Annex A, Special three character coding of resistance value with three
significant numerals.
The text of this standard is based on the following documents:

MARKING CODES FOR RESISTORS AND CAPACITORS



1 Scope
This International Standard specifies designation and marking codes for capacitors and
resistors.
It provides coding methods for the resistance or capacitance value and its tolerance, including
colour coding for resistors.
It provides coding for parameters specific either to capacitors, like e.g. the dielectric material,
or to resistors, like e.g. the temperature coefficient of resistance (TCR).
It also provides date code systems suitable for the marking of small components.
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.

3 Colour code for fixed resistors
3.1 General rules
Colour code is applied in a sequence of individual solid colour bands.
The first band shall be the one nearest to the end of the resistor and the bands shall be so
placed and spaced that there can be no confusion in reading the coding.
The width of the band used for marking the tolerance shall be 1,5 times to 2 times the width of
the other bands in order to avoid any confusion.
Any additional coding shall be so applied as not to confuse the coding for value and tolerance.
Although colour bands are expected to be complete rings around the perimeter of a cylindrical
resistor body, incidental interruption of a band shall be permissible if at least two thirds of the
band is visible from any radial angle of view.
3.2 Prescription of code colours
The colours black, brown, red, orange, yellow, green, blue, violet, grey and white are used for
the coding of the figures 0 through 9 for each significant numeral. Complemented with the
colours silver and gold, they are also used for the coding of the multiplier, the tolerance and

purpose of consistent illustration only.

3.3 Methods for marking resistance value and tolerance
3.3.1 Marking of resistance values with two significant numerals
Resistors with a tolerance of ±20 %, whose resistance values are described with two
significant numerals, are marked with a three-band colour code, consisting of two bands for
the significant numerals, followed by one band for the multiplier. The absence of the fourth
band indicates the tolerance of ±20 %. Figure 1 illustrates this with a 6,8 kΩ resistor with a
tolerance of ±20 %.

3.3.2 Marking of resistance values with two significant numerals and tolerance
Resistors with a tolerance tighter than ±20 %, whose resistance values are described with two
significant numerals, are marked with a four-band colour code, consisting of two bands for the
significant numerals, followed by one band for the multiplier, followed by the last and wider
band showing the tolerance. Figure 2 illustrates this with a 750 kΩ resistor with a tolerance of

3.4 Methods for TCR marking
Colour-code marking of the temperature coefficient shall only be used in combination with a
resistance coding for three significant numerals and is additional to the marking of resistance
value and tolerance as prescribed in 3.3.3.
One of the following methods should be used for the indication of temperature coefficients
with a code colour as prescribed in Table 1, where the tolerance band is consistently
maintained as the single wider band.
a) The TCR is marked by means of a colour band as the sixth band, as shown in Figure 4.
