SFR16S, SFR25, SFR25H www.vishay.com Vishay BCcomponents Standard Metal Film Leaded Resistors FEATURES • Small size (SFR16S: 0204, SFR25 / SFR25H: 0207) • Low noise (max. 1.5 μV/V for R > 1 M) • Compatible to both lead (Pb)-free and lead containing soldering processes • Material categorization:  for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS • General purpose resistors 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 IEC 60068-2-45.
