Abstract :
A new positive temperature coefficient (PTC)resistor and its properties are described which utilizes the metal-insulator solid-state transition in (V,Cr)2 03 . At a transition temperature of 80°C, for example, the specific resistivity of a ceramic body exhibits a · rapid increase to a value 100 times higher than that at 20°C, which is typically 1.5x 10-3 
cm. Due to this low resistivity, thermistors with resistance values between at least 0.1 m and 0.1 can be manufactured which can carry rated currents substantially higher than 200 A or lower than 2 A, respectively. The construction of the new device is described, and typical properties and applications are illustrated.
