Abstract
Abstract A distributed RC component wherein alternate layers of a resistive material and a conductive material are separated by and embedded within a dielectric material. The result is a monolithic body having both resistive and capacitive capabilities and which functions as a filter circuit, a second embodiment has one of the capacitive and resistive layers embedded on a surface of the dielectric.
