| 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 TECHNICAL SPECIFICATIONS DESCRIPTION Resistance range VALUE SFR16S 5 %; 1 to 3 M 1 %; 4.99 to 3 M jumper (0 ) Resistance tolerance Temperature coefficient: R < 4.7 4.7 R 100 k 100 k < R 1 M R > 1 M Absolute maximum dissipation at Tamb = 70 C Thermal resistance, Rth Maximum permissible voltage Noise: R < 68 k 68 k R 100 k 100 k R 1 M R > 1 M Basic specifications Climatic category (IEC 60068) Stability, R/R max., after: load: R range climatic tests: R 1 M R > 1 M Soldering Short time overload www.vishay.com 32 1 % + 0.05 1 % + 0.05 0.25 % + 0.05 0.25 % + 0.05 1 % + 0.05 1 % + 0.05 0.25 % + 0.05 0.25 % + 0.05 1 % + 0.05 2 % + 0.1 0.25 % + 0.05 1 % + 0.05 Document Number: 28722 Revision: 08-Dec-05 2 % + 0.05 2 % + 0.05 2 % + 0.05 max. 0.1 V/V max. 0.5 V/V max. 1.5 V/V max. 1.5 V/V max. 0.1 V/V max. 0.1 V/V max. 0.1 V/V max. 1.5 V/V IEC 60115-1 and 60115-2 55/155/56 max. 0.1 V/V max. 0.1 V/V max. 0.1 V/V max. 1.5 V/V 250 x 10-6/K 100 x 10-6/K 250 x 250 x 10-6/K 10-6/K 100 x 10-6/K 100 x 10-6/K 100 x 250 x 10-6/K 10-6/K 100 x 10-6/K 100 x 10-6/K 100 x 10-6/K 250 x 10-6/K 0.5 W 150 K/W 350 V SFR25 1 %; 1 to 10 M jumper (0 ) 1 %, E24/E96 series; 5 %, E24 series SFR25H 5 %; 0.22 to 10 M 0.5 W 170 K/W 200 V 0.4 W 200 K/W 250 V For technical questions contact: ff3dresistors@vishay.com 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 or 7 digits indicate the resistor type and packing. * 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.
