    摘要: An integral plated resistor having an improved range of resistance is produced by uniformly dispersing an effective amount of various particles in an electroless nickel phosphorus plating composition so that the particles are codeposited with the electroless nickel phosphorus plating composition. Preferred particles include, polytetrafluoroethylene, silicon carbide, tungsten carbide, and other particles that fully sinter at a temperature of less than about 170° C. The improved nickel phosphorus plated resistors of the invention demonstrate increased stability during manufacturing press cycles and a greater range of resistance values than have previously been achieved.
