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.
