VISHAY SFR25

SFR16S/25/25H
Vishay BCcomponents
Standard Metal Film Resistors
FEATURES
• Low cost
• Low noise
• Small size (SFR16S)
• Lead (Pb)-free solder contacts
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”.
• 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

The length of the body (L1) is measured by inserting the
leads into holes of two identical gauge plates and moving
these plates parallel to each other until the resistor body is
clamped without deformation (“IEC publication 60294”).
MARKING
The nominal resistance and tolerance are marked on the
resistor using four or five coloured bands in accordance with
IEC publication 60062 “Color codes for fixed resistors”.
FUNCTIONAL PERFORMANCE
PRODUCT CHARACTERIZATION
Standard values of nominal resistance are taken from the E96/E24 series for resistors with a tolerance of ± 1 % or ± 5 %.
The values of the E96/E24 series are in accordance with “IEC publication 60063”.

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 description of the test procedure is also given. In some
instances deviations from the IEC recommendations were
necessary for our method of specifying.
