DESCRIPTION
A metal glazed film is deposited on a
high grade ceramic body. After a
helical groove has been cut in the
resistive layer, tinned electrolytic
copper wires are welded to the
end-caps. The resistors are coated
with a light blue lacquer which
provides electrical, mechanical, and
climatic protection.
The encapsulation is resistant to all
cleaning solvents in accordance with
鈥淢IL-STD 202E, method 215鈥?/div>
and
鈥淚EC 60068-2-45鈥?
