FEATURES
DESCRIPTION
• Low cost
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.
• Low noise
• Small size (SFR16S).
APPLICATIONS
• General purpose resistors.

mechanical and climatic protection.
The encapsulation is resistant to all
cleaning solvents, in accordance with
“MIL-STD-202E, method 215”, and
“IEC 60068-2045”.
The resistors are coated with a

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.
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.
