摘要（英）：

The invention belongs to the field of alloy foil resistors. The invention discloses a high-precision chip type alloy foil fixed resistor which is a surface-mounted resistor and takes an alloy foil serving as block metal as a resistance layer material. A specially-designed fine alloy foil pattern is formed through photoetching, and then the resistance value and the precision are trimmed through precision laser resistance adjustment. A protective layer covers the surface of the alloy foil chip. The alloy foil chip is electroplated to form a leading-out end. SMD and miniaturization of a high-precision alloy foil product are realized. According to the invention, four models of resistors are provided including RM2012: 2.0 mm * 1.2 mm * 0.6 mm, RM3216: 3.2 mm * 1.6 mm * 0.6 mm, RM5025: 5.0 mm *2.5 mm * 0.6 mm, and RM6332: 6.3 mm * 3.2 mm * 0.6 mm.
