SFR16S/25/25H
Vishay BCcomponents
Standard Metal Film Resistors
FEATURES
• Low cost • Low noise • Small size (SFR16S) 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”. • 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

OUTLINES
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”.
LIMITING VALUES

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.
