Abstract
An electrical component includes a stack of layers. The layers include dielectric layers and electrode layers. The dielectric layers have a resistance with a positive temperature coefficient. The electrode layers are electrically conductive and are interspersed among the dielectric layers. At least one of the electrode layers includes a constituent that is comprised of a base metal and that is at least partially coated with a protective layer. The protective layer includes a material that slows oxidation of the base metal.
