RESISTOR COMPONENT WITH MULTIPLE LAYERS OF RESISTIVE MATERIAL

摘要

PURPOSE: Resistor component with multiple layers of resistive material is provided to facilitate the formation of a variety of different resistive elements having a variety of resistance values. CONSTITUTION: A resistor foil(10) comprises a copper layer(12) having a first side and a second side. A tiecoat metal layer having a thickness of between 5 and 70 is provided on the first side of the copper layer. A first layer of a first resistor metal having a thickness of between 100 and 500 is on the tiecoat metal layer, and a second layer of a second resistor metal having a thickness of between 100 and 500 is on the first layer of the first resistor metal. The first resistor metal has a resistance different from the second resistor metal.
