Carbon film fixed Resistors Type CFR Series Key Features Low Cost – High Reliability High power to size ratio 5 power ratings – 0.25W ~ 2W Applications Audio Communications Measurement Computing 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.
