DESCRIPTION
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 wires of electrolytic
copper or copper-clad iron are welded to the end-caps. The
resistors are coated with a red, non-flammable lacquer
which provides electrical, mechanical and climatic
protection. This coating is not resistant to aggressive fluxes
and cleaning solvents. The encapsulation is resistant to all
cleaning solvents in accordance with IEC 60068-2-45.
APPLICATIONS
• All general purpose power applications
• Automotive electronics
• Lighting ballast
