The resistive element comprises a thin film of carbon, deposited onto a high thermal con-
ductivity ceramic core. Metal end caps are force fitted to the element prior to spiralling to
value. Tinned copper lead wires are welded to the end caps and the components are then
coated. One coat of phenolic resin is followed by three coats of epoxy resin. All resistors
are tested for value and tolerance.
