CFR50J300R - 

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 spiraling value. Tinned copper lead wires are welded to the end caps and the components are then coated. One coat of phenolic resin followed by three coats of epoxy resin. All resistors are tested for value and tolerance.
