Abstract
A resistive device for use in providing a resistive load to a target under the application of power from a power source is provided, the resistive device being adapted for electrical connection to the power source through a pair of terminal wires. The resistive device includes a thick film material, and the thick film material defines at least one layer of tape. The resistive device can be, by way of example, a heater or a load resistor, and can also include a substrate onto which a layer of dielectric tape is disposed, a resistive layer disposed on the layer of dielectric tape, and a protective layer disposed on the resistive layer.
