The RR Series is manufactured by depositing a homogeneous film of metal alloy onto a
high-grade ceramic body. After a helical groove has been cut in the resistive layer, tinned
connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated
with a red, non-flammable lacquer, which provides electrical, mechanical and climatic pro-
tection. The coating is resistant to all cleaning solvents in accordance with MIL-STD-202,
method 215 and IEC 60068-2-45.
