FEATURES
DESCRIPTION
SFR16S/25/25H
5033E/5043E/5053H
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”.
•
Low cost
•
Low noise
•
Small size (SFR16S).
APPLICATIONS
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
coloured lacquer (light-blue for
•
General purpose resistors.
