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.
