FEATURES
• Reduced size of final equipment
• Low assembly costs
• Higher component and equipment
reliability.
APPLICATIONS
• Camcorders
• Hand held measuring equipment
• Car telephones
• Computer
• Portable radio, CD and cassette
players.
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 coating. Finally, external
end terminations are added. For
ease of soldering the outer layer of
these end terminations is a lead-tin
alloy.

TEST 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, EIAJ
and JIS.
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 °C to 35 °C
Relative humidity: 25% to 75%
Air pressure: 86 kPa to 106 kPa
(860 mbar to 1060 mbar).
