Abstract (en)

[origin: WO2023001856A1] The invention relates to a resistor (1), in particular a thick-film resistor, in particular for a high-voltage system (2) of a motor vehicle, having a nominal power of at least 10 watts, comprising: at least two electrical resistor terminals (8a, 8b); a ceramic substrate (5); and a resistor element (3) which is electrically provided between the two resistor terminals (8a, 8b) and which is made of a thick-film material (4) applied to the ceramic substrate (5), the resistor element (3) having a temperature coefficient (TCR). In order to make it easier to monitor discharge via the resistor (1), according to the invention the temperature coefficient (TCR) is >700 ppm/K, in particular >1000 ppm/K.
