PTC Formulated Powder

PTC (Positive Temperature Coefficient) Thermistor is a semiconducting ceramic element which is made from Barium Titanate as the main materials. It has the feature that resistance value will make a sudden change accompanying with the rising of the temperature after arriving the Currie point. PTC Thermistor ceramics. And Curie temperature is -50°C-320°C Electrical Resistivity is in the range from 5Ω.cm to 50kΩ.cm. Ceramic matched with PTC thermistor ceramic contains degausser of CRT, motor stater of fridge and air-conditioner, over current protection, temperature compensation, constant temperature heater and PTC in SMD style.PTC Formulated Powder Specification                  TypeCurie Temperature (°C)Resistivity at 25°C(Ω.cm)Broken Voltage (V/mm)N5*B-50±5100-5,000>25P0*E0±5100-5,000>25P2*E20±520-1,000>25P4*E40±520-100>220P5*E50±520-100>220P6*E60±520-100>220P7*E70±520-300>220P8*E80±520-300>220P9*E90±520-300>220
