Abstract

Ein elektrischer Widerstand (6) weist eine Platin oder ein Platingruppenmetall enthaltende Widerstandsschicht auf, die auf einer elektrisch isolierenden Oberfläche eines Substrats (4) aufgebracht ist, wobei die Widerstandsschicht als Dünnschicht-Element ausgebildet ist und eine physikalische Mischung aus feindispergierter Keramik und Metall aufweist; vorzugsweise liegt das Verhältnis von feindispergierter Keramik zu Metall in Gewichts-% im Bereich von 5 bis 50%.
Als feindispergierte Keramik wird vorzugsweise SiO, SiO2, Ta2O5, MgO, Al2O3, oder eine Mischung daraus eingesetzt.
Der erfindungsgemäße Widerstand wird als Referenz-Widerstand (6) in einem Sensor (Temperatur-Sensor) zusammen mit einem temperaturabhängigen Messwiderstand (5) eingesetzt, wobei beide Widerstände auf einem gemeinsamen Substrat (4) angeordnet sind.
