FEATURES
DESCRIPTION
œ Low assembly costs
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.
œ High component and equipment
reliability
œ Excellent performance at high
frequency, especially the RC32.
œ TC 50 in thick film technology
œ Complete precision SMD family.
APPLICATIONS
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.
œ All general purpose applications.

FUNCTIONAL DESCRIPTION

Product characterization
The power that the resistor can dissipate depends on the operating
temperature; see Fig.1.
Standard values of nominal
resistance are taken from the
E24/E96 series for resistors with a
tolerance of –1%. The values of the
E24/96 series are in accordance with
“IEC publication 60063”.

All soldering tests are performed with mildly activated flux.
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.
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
Relative humidity: 45% to 75%
Temperature: 15 •C to 35 •C
Unless otherwise specified the following values apply:
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.
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
