FEATURES
Low cost
Low noise (max. 1.5 µV/V for
R
> 1 MΩ)
Small size (SFR16S-0204, SFR25/25H-0207)
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”.
Lead (Pb)-free solder contacts
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)
