Abstract
Abstract A sensor for detecting a rapid temperature rise comprises a thermistor chip electroded on opposing faces and having lead-in wires electrically connected to the faces. The thermistor chip is encapsulated between two ribbons of plastic film which, in turn, are encapsulated between two sheets of copper foil which, in turn, are encapsulated between two layers of plastic film.
