please see www.vishay.com/doc?99912
A homogenous film of metal alloy 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
blue, non-flammable lacquer, which provides electrical,
mechanical, and climatic protection.
APPLICATIONS
• Power supplies
• Electronic ballast
• White goods
• Television
