SFR16S/25/25H Vishay BCcomponents Standard Metal Film Resistors FEATURES * Low cost * Low noise (max. 1.5 V/V for R > 1 M) * Small size (SFR16S-0204, SFR25/25H-0207) * 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 TECHNICAL SPECIFICATIONS VALUE DESCRIPTION SFR16S Resistance Range SFR25 SFR25H 5 %; 1 to 3 M 5 %; 0.22 to 10 M 1 %; 4.99 to 3 M 1 %; 1 to 10 M jumper (0 ) Resistance Tolerance jumper (0 ) 1 %, E24/E96 series; 5 %, E24 series Temperature Coefficient: R < 4.7 250 x 10-6/K 100 x 10-6/K 100 x 10-6/K 4.7 R 100 k 100 x 10-6/K 100 x 10-6/K 100 x 10-6/K 100 k < R 1 M 250 x 10-6/K 100 x 10-6/K 100 x 10-6/K R > 1 M 250 x 10-6/K 250 x 10-6/K 250 x 10-6/K Absolute Maximum Dissipation at Tamb = 70 C 0.5 W 0.4 W 0.5 W 170 K/W 200 K/W 150 K/W 200 V 250 V 350 V R < 68 k max. 0.1 V/V max. 0.1 V/V max. 0.1 V/V 68 k R 100 k max. 0.5 V/V max. 0.1 V/V max. 0.1 V/V 100 k R 1 M max. 1.5 V/V max. 0.1 V/V max. 0.1 V/V R > 1 M max. 1.5 V/V max. 1.5 V/V max. 1.5 V/V Thermal Resistance, Rth Maximum Permissible Voltage Noise: Basic Specifications IEC 60115-1 and 60115-2 Climatic Category (IEC 60068) 55/155/56 Stability, R max., After: Load: R range (2 % R + 0.05 ) (2 % R + 0.05 ) (2 % R + 0.05 ) Climatic Tests: R 1 M (1 % R + 0.05 ) (1 % R + 0.05 ) (1 % R + 0.05 ) R > 1 M (1 % R + 0.05 ) (1 % R + 0.05 ) (2 % R + 0.1 ) Soldering (0.25 % R + 0.05 ) (0.25 % R + 0.05 ) (0.25 % R + 0.05 ) Short Time Overload (0.25 % R + 0.05 ) (0.25 % R + 0.05 ) (1 % R + 0.05 ) Note: * R value is measured with probe distance of 24 1 mm using 4-terminal method www.vishay.com 34 For technical questions, contact: filmresistors.leaded@vishay.com Document Number: 28722 Revision: 20-Feb-08 SFR16S/25/25H Standard Metal Film Resistors Vishay BCcomponents 12NC INFORMATION * The resistors have a 12-digit numeric code starting with 23. * The subsequent 6 digits for 1 % or 7 digits for 5 % indicate the resistor type and packaging. * The remaining digits indicate the resistance value: - The first 3 digits for 1 % or 2 digits for 5 % indicate the resistance value. - The last digit indicates the resistance decade.

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.
