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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

The following information shall be given in each detail specification and the values quoted
shall preferably be selected from those given in the appropriate clause of this sectional
specification.
1.4.1 Outline drawing and dimensions
There shall be an illustration of the surface mount resistor network as an aid to easy
recognition and for comparison of the surface mount resistor network with others.
Dimensions and their associated tolerances, which affect interchangeability and mounting,
shall be given in the detail specification. All dimensions shall be stated in millimetres.
Normally the numerical values shall be given for the length, width and thickness of the body.
Schematic diagrams and pin identifications shall be given in the detail specification. Those
are prescribed in Annex A.
Configurations of terminations shall be given in the detail specification. Those are prescribed
in Annex B.
When the outline drawing is other than described above, the detail specification shall state
such dimensional information as will adequately describe the surface mount resistor network.
1.4.2 Mounting
The detail specification shall give guidance on methods of mounting for normal use. Mounting
for test and measurement purposes (when required) shall be in accordance with 4.31 of
IEC 60115-1.

1.4.4 Ratings and characteristics
The ratings and characteristics shall be in accordance with the relevant clauses of this
specification together with the following:
Rated resistance range
See 2.2.1. The preferred values are those of the E-series of IEC 60063.
NOTE When products approved to the detail specification have different ranges, the following statement should
be added:
“The range of values available in each style is given in the qualified products list”.
1.4.5 Marking
The detail specification shall specify the content of the marking on the surface mount resistor
network and on the package.
Surface mount resistor networks are generally not marked on the body. If some marking can
be applied, the surface mount resistor network shall be clearly marked with the rated
resistance and as many of the remaining items in 2.4 of IEC 60115-1 as possible.
All items shall be marked on the package. Deviations from the above mentioned requirements
shall be specifically stated.
2 Preferred ratings, characteristics and test severities
2.1 Preferred ratings and characteristics
The values given in detail specifications shall preferably be selected from the following:
2.1.1 Preferred climatic categories
The surface mount resistor networks covered by this specification are classified into climatic
categories according to the general rules given in IEC 60068-1.
The lower and upper category temperature and the duration of the damp heat, steady state
shall be chosen from the following:
Lower category temperature: –55 °C, –40 °C, –25 °C and –10 °C.
Upper category temperature: +85 °C, +100 °C, +125 °C and +155 °C.
Duration of the damp heat, steady state test: 4, 10, 21 and 56 days.
The severities for the cold and dry heat tests are the lower and upper category temperatures
respectively. Because of the construction of some surface mount resistor networks these
temperatures will occur between two of the preferred temperatures given in IEC 60068-2-1
and IEC 60068-2-2. In this event, the nearest preferred temperature within the actual
temperature range of the surface mount resistor network shall be chosen for this severity.
2.1.2 Temperature coefficients and temperature characteristics of resistance
The preferred limits of change in resistance for the temperature characteristics of resistance
test are given in Table 2.

---------------------- Page: 10 ----------------------

Each line in the table gives the preferred temperature coefficient and corresponding
temperature characteristic for 20 °C to 70 °C and limits of change in resistance for the
measurement of the temperature characteristic of resistance (see 4.8 of IEC 60115-1) on
the basis of category temperature ranges of 2.1.1 of this sectional specification.
