An electrical device which contains a first electrode, a second electrode, a third electrode, a first resistor which is connected in series between the first and second electrodes, and a second resistor which (i) is thermally coupled to the first resistor, (ii) exhibits anomalous resistance/temperature behavior, and (iii) is connected in series between the first and third electrodes. The device has at least one of the following characteristics: (a) the first resistor and at least one of the first and second electrodes are formed from a single piece of metal; (b) the device has a generally planar configuration and comprises at least one electrical connector connected to one of the first, second, and third electrodes, whereby the first, second and third electrodes or connectors secured thereto can be secured directly to a circuit board with the device parallel to the circuit board; and (c) the second resistor is a planar sheet of a material which exhibits anomalous resistance/temperature behavior, the sheet having a first major surface to which the first and second electrodes are attached and a second major surface to which the third electrode is attached. The device can be prepared from an electrical assembly which can be divided into a plurality of devices. |
