ABSTRACT:
A surge r or network comprises a substrate layer having a first thick film resistive element, a dielectric layer covering the first thick film resistive element and a second thick film resistive element applied to the dielectric layer. The dielectric layer has a pair of vias that extend therethrough so that the first resistive element is electrically connected to the second resistive element through the vias. A pair of electrical terminals are coupled to the first resistive layer at the substrate. The first resistive element comprises a first pair of unconnected adjacent tracks that each spiral respectively inward in a serpentine pattern. Each one of the tracks has an electrical pad disposed at a first end thereof for attachment to respective ones of the pair of electrical terminals. A second end of the tracks is disposed at a center of each serpentine pattern. The second resistive element comprises a second pair of adjacent tracks that each spiral respectively outward in a serpentine pattern. Each one of the second pair of tracks are coupled to respective ones of the vias at respective ends thereof at a center of each serpentine pattern. The second pairs of tracks are joined together at a trim region disposed between the adjacent tracks.
