PTCR(Positive Temperature Coefficient of Resistivity) thermally sensitive ceramics, which is low Resistance at room temperature, the resistivity increase drastically at its curie temperature, the range of curie temperature is about 30~300℃. Rmax/Rmin is about 103~107 and temperature coefficient≥20% / ℃, is widely used in self-requlation heating and temperature protecting.
