Circuit arrangement for the detection of an excess temperature due to a current flowing

The present invention pertains to a circuit configuration designed to detect excess temperature due to current flow, with thermal coupling of a first resistor arrangement and a second resistor arrangement, the amount of resistance of the second resistor arrangement producing a thermistor action. The current to be evaluated flows through at least the first resistor arrangement. The first resistor arrangement consists of at least one SMD resistor and the second resistor arrangement of at least one SMD resistor that acts as a thermistor. The second resistor arrangement is electrically connected to at least one contact surface of the printed circuit board, which is connected to the at least one SMD resistor of the first resistor arrangement.
