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 resist or values ar e
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.

Application information
TRIMMING INSTRUCTIONS WITH YAG-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.
PROTECTION 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, lon g
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 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).
