FEATURES
DESCRIPTION
type SFR16S; light-green for type
SFR25 and red-brown for type
SFR25H) which provides electrical,
mechanical and climatic protection.
The encapsulation is resistant to all
cleaning solvents, in accordance with
“MIL-STD-202E, method 215”, and
“IEC 60 068-2045”.
• 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
The resistors are coated with a
coloured lacquer (light-blue for
• General purpose resistors.

TESTS AND REQUIREMENTS
In Table 5 the tests and requirements are listed with reference to the
relevant clauses of “IEC publications 60115-1 and 60 068-2”; 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.
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 6 0068-2,
“Recommended basic climatic and mechanical robustness testing
procedure for electronic components” and under standard atmospheric
conditions according to “IEC 60068-1”, subclause 5.3.
