An electrical resistor has a resistance layer containing platinum or a platinum group metal, which is applied to an electrically insulating surface of a substrate, wherein the resistance layer is constructed as a thin layer element and is made of a physical mixture of finely dispersed ceramic and metal. Preferably, the ratio of finely dispersed ceramic to metal lies in a range of about 5 to 50% by weight. Preferably, the finely dispersed ceramic is selected from SiO, Sio2, Ta2O5, MgO, Al2O3, and mixtures thereof. The resistor is used as a reference resistor in a sensor (temperature sensor) together with a temperature-dependent measuring resistor, wherein both resistors are arranged on a common substrate.
An electrical resistor comprising a resistance layer containing a platinum metal, the resistance layer being applied on an electrically insulating surface of a substrate, wherein the resistance layer is constructed as a thin layer element having a layer thickness in a range of about 0.1 μm to 2 μm, wherein the resistance layer comprises a physical mixture of finely dispersed ceramic and metal, and wherein the weight ratio of ceramic to metal lies in a range of about 5:95 to 50:50.
An electrical resistor comprising a resistance layer containing a platinum metal, the resistance layer being mounted on an electrically insulating surface of a substrate, wherein the resistance layer is constructed as a thin layer element having a layer thickness in a range of about 0.1 μm to 2 μm, and wherein thin layer element comprises a physical mixture of finely dispersed ceramics and a platinum metal compound.
