Carbon Film Fixed Resistors Type CFR Series Key Features Low cost, combined with high reliability, make these components suitable for use in most types of circuits, including audio, communications, measurement and computer applications. Premium quality carbon film resistors whose ceramic core has a high alumina content offering power to size ratios not normally associated with carbon film product. Available in 5 power ratings from 1 ohm to 10 Mohm. The smallest case size (CFR16) has a full 0.25 W power rating. 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. Characteristics Electrical Rated Power @ 70 C (W) Resistance Range (Ohms) Tolerance (%) Code letter Temp.
