Abstract:
One aspect is a resistor component for surface mounting on a printed circuit board, including a ceramic substrate with a first side and an opposite second side. A sinterable metallization is at least in some regions arranged on the second side. A resistance element comprising a metal layer is arranged at least in some regions on the first side of the ceramic substrate with a first connection and a second connection. An insulation layer is arranged at least in some regions on the resistance element and the ceramic substrate. A first region on the first connection and a second region on the second connection remain uncovered by the insulation layer. A first contact pad electrically contacts the first connection via the first region, and a second contact pad electrically contacts the second connection via the second region. The first contact pad at least in some regions covers a first surface region of the insulation layer and the second contact pad at least in some regions covers a second surface region of the insulation layer, and the first and the second contact pads are arranged spatially separated from one another on the insulation layer.
