Abstract A multilayer electronic component (200) is provided. The component includes a substrate package assembly (202) with a set of stacked insulated sheets of a dielectric ceramic material (204, 206, 208, 210, 212). Also included are a set of embedded resistors (214), each of the embedded resistors including an electrical input port pad (216) and an electrical output port pad (218) provided in layers between the set of stacked insulated sheets. Each of the insulated sheets has a trough (220) of a predetermined length aligned between and transverse to the electrical input port pad (216) and the electrical output port pad (218). The trough (220) reduces the resistance value variability in the multilayer electronic component (200). The trough (220) is substantially filled with a resistive paste material and an internal circuit (222) connects the embedded resistors inside the substrate package assembly (202). A method of forming the substrate package assembly (202) is also provided.
A multilayer electronic component, comprising: a substrate package assembly comprising a plurality of stacked insulated sheets of a dielectric ceramic material; a plurality of horizontally embedded resistors, each of the horizontally embedded resistors defining a resistor formed in only one discrete layer of the substrate package and comprising: an electrical input port pad and an electrical output port pad on a single layer of the plurality of stacked insulated sheets; a trough having a predetermined length and a predetermined width filled with a resistive paste material and providing a uniform resistance across the electrical input port pad and the electrical output port pad; and an internal circuit connecting the plurality of horizontally embedded resistors.
