PTC ceramic thermistor ρ-T curve分子式：CAS号：性质：描述正温度系数热敏陶瓷电阻率与温度关系的曲线。钛酸钡基PTC热敏陶瓷阻-温特性曲线。电阻率随着温度的升高，先是降低，当达到某一值Tmin时，曲线出现极值，经过极值后电阻率随温度升高而急剧上升，此时对应的温度Tb称为开关温度。电阻率随温度上升达到最大值时所对应的温度为Tm。经过Tm后，阻温特性曲线发生弯曲，电阻率开始逐步降低，此时对应的温度为Tp。温度处于Tb至Tm之间时，热敏陶瓷呈现正温度系数(PTC)特性。其电阻温度系数αT= ，式中Rb，Rp为Tb，Tp温度下的相应零功率电阻值。αT大于10％/℃，为开关型热敏陶瓷电阻器。αT小于10％/℃，为缓变型热敏陶瓷电阻器。
