The CFR16J1K0 is a 1kR Carbon Film Fixed Resistor 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.
High reliability
Carbon film resistors whose ceramic core has high alumina content offering power to size ratios
