The LR0204F1K0 is a 1kΩ Metal Film Fixed Resistor with 1% tolerance and 0.25W power rating. The resistive element comprises a thin film of nickel-chrome alloy evaporated onto a high thermal conductivity ceramic element. 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.
