PURPOSE: To provide a compact positive temperature conefficient thermistor which has a large positive temperature coefficient of resistance immediately after Curie temperature. CONSTITUTION: A positive temperature coefficient thermistor which has a large positive temperature coefficient of resistance immediately after Curie temperature and is capable of suppressing growth of crystal grains is made from a material that contains 0.09-0.125mol of CaTiO3 to 1mol of barium titanate ceramic semiconductor and. |
