Standard Metal Film 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 “MIL-STD-202E,
method 215”, and “IEC 60068-2045”.
FEATURES
• Low cost
• Low noise
• Small size (SFR16S)
• 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)
APPLICATIONS
• General purpose resistors
