* Low cost * Low noise * Small size (SFR16S).
APPLICATIONS
A homogeneous 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 leads of electrolytic copper are welded to the end-caps. The resistors are coated with a coloured lacquer (light-blue for

TESTS AND REQUIREMENTS Essentially all tests are carried out in accordance with the schedule of "IEC publication 60115-1", category 55/155/56 (rated temperature range -55 C to +155 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 60068-2, "Recommended basic climatic and mechanical robustness testing procedure for electronic components" and under standard atmospheric conditions according to "IEC 60068-1", subclause 5.3. Table 7 Test procedures and requirements IEC 60068-2 TEST METHOD 21 (U) 21 (Ua1) 21 (Ub)
In Table 7 the tests and requirements are listed with reference to the relevant clauses of "IEC publications 60115-1 and 60068-2"; 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.
