DESCRIPTION
The resistors are constructed on a
high grade ceramic body (aluminium
oxide). Internal metal electrodes are
added at each end and a connection
is made between them using a
resistive metal glaze; the
approximate resistor values are
dependent on the composition of the
glaze.
The resistive layer is covered with a
translucent protective coat. Finally,
two end electrodes are added, the
composition of which has been
designed to provide ease of
soldering.

LASER
Typical values for:
Cutting speed = 10 to 300 mm/s
Laser power = 1 to 6 W
Maximum trimming length = 60% of resistor film width
Minimum distance between end termination and trimming cut = 0.20 mm.
P
ROTECTION OF LASER CUT
With epoxy-phenol lacquers, epoxy resins or silicon alkyd-resins.
This is necessary for humidity tests and stability at load.

TEST AND REQUIREMENTS
Essentially all tests are carried out in
accordance with the schedule of
“IEC publication 60115-8”,
category
55/125/56 (rated temperature range
−55
to
+125 °C;
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
Table 3
testing procedure for electronic
components”
and under standard
atmospheric conditions in
accordance with
“IEC 60068-1”,
subclause 5.3.
Unless otherwise specified the
following values apply:
Temperature: 15
°C
to 35
°C
Relative humidity: 45% to 75%
Air pressure: 86 kPa to 106 kPa
(860 mbar to 1060 mbar).
RC22TR
In Table 3 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.
