Standard Metal Film Resistors
www.DataSheet4U.com
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 colored lacquer (light-blue for
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 60068-2045”.
FEATURES
• Low cost
• Low noise
• Small size (SFR16S)
• Lead (Pb)-free solder contacts
• Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
• Compatible with “Restriction of the use of Hazardous
Substances” (RoHS) directive 2002/95/EC (issue 2004)
APPLICATIONS
• General purpose resistors

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.
In the Test Procedures and Requirements table the tests and
requirements are listed with reference to the relevant clauses
of “IEC publications 60115-1 and 60068-2”; a short des-
cription of the test procedure is also given. In some
instances deviations from the IEC recommendations were
necessary for our method of specifying.
