A material for use as part of an internal resistor within a circuitized substrate includes a polymer resin and a quantity of nano-powders including a mixture of at least one metal component and at least one ceramic component. The ceramic component may be a ferroelectric ceramic and/or a high surface area ceramic and/or a transparent oxide and/or a dope manganite. Alternatively, the material will include the polymer resin and nano-powders, with the nano-powders comprising at least one metal coated ceramic and/or at least one oxide coated metal component. A circuitized substrate adapted for using such a material and resistor therein and a method of making such a substrate are also provided. An electrical assembly (substrate and at least one electrical component) and an information handling system (e.g., personal computer) are also provided.
