SFR16S/25/25H Vishay BCcomponents Standard Metal Film Leaded Resistors FEATURES Low cost Low noise (max. 1.5 V/V for R > 1 M) Small size (SFR16S: 0204, SFR25/25H: 0207) A homogeneous film of metal alloy is deposited on a high Lead (Pb)-free solder contacts grade ceramic body. After a helical groove has been cut in Pure tin plating provides compatibility with lead (Pb)-free the resistive layer, tinned connecting leads of electrolytic and lead containing soldering processes copper are welded to the end-caps. The resistors are coated with a colored lacquer (light-blue for Compliant to RoHS directive 2002/95/EC type SFR16S light-green for type SFR25 and red-brown for type SFR25H) which provides electrical, mechanical and APPLICATIONS climatic protection. The encapsulation is resistant to all General purpose resistors cleaning solvents in accordance with IEC 60068-2-45.
