ABSTRACT:
A thick film resistor element capable of dissipating relatively large amounts of microwave energy comprises several distinct layers of resistive material overlying an electrically insulating thermally conducting substrate. The final dimensions of the element can be made comparatively small with respect to a conventional element having comparable dissipation capability. The element has a coating of a crossover dielectric material which provides a moisture barrier between the element and the ambient.
