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.
