Abstract
A resistor component is provided, including a ceramic bar having a film applied thereon, a protection layer formed on the film in a middle portion of the ceramic bar, an end plating layer formed on the film at two ends of the ceramic bar, an insulation layer formed on the protection layer, and a color coded marking formed on the insulation layer that indicates the resistance of the resistor component. The end plating layer is formed by a barrel plating method and includes copper, tin, nickel and a combination thereof. The resistor component thus has a low cost and is manufactured by a simple process, simultaneously avoids the occurrence of pores or incompletely sealed join that may be caused by the prior method. Therefore the resistor component has high reliability.
