摘要： An R-C network formed on a substrate. The capacitor includes a metal member with anodized and unanodized layers. The unanodized layer functions as one of the capacitor's electrodes. The anodized layer functions as the capacitor's dielectric layer. The resistor is formed from material on the same side of the substrate as the capacitor. In some versions of the invention, the resistor is formed on top of a substrate dielectric layer. In these versions of the invention, a conductor both functions as one of the capacitor's electrodes and connects the resistor to the capacitor. In alternative versions of the invention, the resistor is formed from a film that disposed on the undersurface a metal foil. The foil functions as the resistor to capacitor conductor. Sections of the foil that are removed expose and define the resistor. Solder balls or other connectors on the substrate surface connect the network to another component.

摘要： Conductive material is applied to a resistor to provide controlled shunting of current from localized regions of the resistor that would otherwise destructively fail during surge. Various embodiments are disclosed having varying resistance, dimension and placement. The continuity of the original resistor material is not altered, nor is the current diverted in such as way as to create a new localized regions that might destructively fail. The resistors so designed have application in lightning surge environments, power supply and power input circuitry and other applications where potential short duration surges might otherwise cause destructive failure of standard resistors.
