High Precision Thin Film Leaded Resistors
FEATURES
•
High precision resistors
(TCR up to ± 5 ppm/K, 0.01 % tol.)
•
High stability (0.05 %)
•
Low temperature coefficient (up to ± 5 ppm/K)
•
Lead (Pb)-free solder contacts
•
Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
•
Compliant to RoHS directive 2002/95/EC
DESCRIPTION
A homogenous film of metal alloy is deposited on a high
grade ceramic body. After a helical groove has been cut in
the resistive layer, tinned connecting wires of electrolytic
copper are welded to the end-caps. The resistors are coated
with lacquer which provides electrical, mechanical, and
climatic protection.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
following specifications:
EN 60115-1, Generic specification (includes tests)
EN 140100, Sectional specification (includes schedule for
qualification approval)
CECC 40101-806, Detail specification (includes schedule for
conformance inspection)
Most of the components are approved in accordance with the
European CECC-system, where applicable. The following
table contains only the most important tests. For the full test
schedule refer to the documents listed above. The testing
also covers most of the requirements specified by
EIA/IS-703 and JIS-C-5202.
The tests are carried out in accordance with IEC 60068-2-xx
test method and under standard atmospheric conditions in
accordance with IEC 60068-1, 5.3. Climatic category
LCT/UCT/56 (rated temperature range: Lower category
temperature, upper category temperature; damp heat, long
term, 56 days) is valid.
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).
For testing the components are mounted on a test board in
accordance with IEC 60115-1, 4.31 unless otherwise
specified.
In the Test Procedures and Requirements table only the
tests and requirements are listed with reference to the
relevant clauses of IEC 60115-1 and IEC 60068-2-xx test
methods. A short description of the test procedure is also
given.
