More Information
Summary:A positive temperature coefficient thermistor formed of a principal ingredient comprising barium titanate, lead titanate and calcium titanate, and rare earth elements, being particularly characterized by using calcium titanate as a raw material and having the particle diameter of said calcium titanate among raw material powders made smaller than that of other raw materials. The positive temperature coefficient thermistor formed by the present invention has improved durability in a reducing atmosphere due an increased density of the crystal structure.
