The resistive element comprises a thin film of carbon, deposited onto a high thermal
conductivity 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.
