FEATURES
Low assembly costs
High component and equipment
reliability
Excellent performance at high
frequency, especially the RC32.
TC 50 in thick film technology
Complete precision SMD family.
APPLICATIONS
All general purpose applications.
DESCRIPTION
The resistors are constructed on a
high grade ceramic body (aluminium
oxide). Internal metal electrodes are
added at each end and connected by
a resistive paste which is applied to
the top surface of the substrate. The
composition of the paste is adjusted
to give the approximate resistance
required and the value is trimmed to
within tolerance, by laser cutting of
this resistive layer.
The resistive layer is covered with a
protective coat and printed with the
resistance value (no printing on
RC22H and RC32). Finally, the two
external end terminations are added.
For ease of soldering the outerlayer of
these end terminations is a lead/tin
alloy.

Marking
All resistors except RC22 and RC32
are marked with a four digit code on
the protective coat to designate the
nominal resistance value.
4-DIGIT MARKING
For values up to 976 W the R is used
as a decimal point. For values of 1 kW
or greater the first 3 digits apply to the
resistance value and the fourth
indicates the number of zeros to
follow.
Example
PACKAGE MARKING
The packing is marked with the
resistance value, tolerance,
catalogue number, quantity,
production period, batch number and
source code.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the schedule of “IEC publication 60115-8”, category LCT/UCT/56 (rated temperature range:
Lower Category Temperature, Upper Category Temperature; damp heat, long term, 56 days). The testing also covers the requirements specified by
EIA and EIAJ.
The tests are carried out in accordance with IEC publication 60068, “Recommended basic climatic and mechanical robustness testing procedure for
electronic components” and under standard atmospheric conditions according to “IEC 60068-1”, subclause 5.3.
Unless otherwise specified the following values apply:
Temperature: 15 Cto35C
Relative humidity: 45% to 75%
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
In Table 4 the tests and requirements are listed with reference to the relevant clauses of “IEC publications 60115-8 and 60068”; a short description of
the test procedure is also given. In some instances deviations from the IEC recommendations were necessary for our method of specifying.
All soldering tests are performed with mildly activated flux.
