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)
