负温度系数热敏电阻器是一种电阻值随着温度的升高而减小的热敏电阻器。其阻值的变化可以由外在的环境温度或是回路中电流引起的组件自热引起。这种电阻值随着温度改变的可预知性是热敏电阻器应用的基础。 NTC (Negative Temperature Coefficient) thermistors are resistors with large negative temperature coefficient. Change in resistance of the NTC thermistors can be brought about either externally by a change in ambient temperature or internally by self-heating resulting from a current flowing through the device. This predictable change in resistance as temperature changes is the basis for all applications of thermistors. 负温度系数热敏电阻器属于半导体的一种，通常是由锰、钴、镍、铜、铁等组成的过渡金属氧化物通过烧结后形成不同的形状和尺寸。通过改变半导体中元素的组成和本体尺寸，室温中产品的阻值范围可以从1 Ω到10⁶ Ω，温度系数从 -2%/Ω到 -6.5%/°C。 The semiconducting material of NTC thermistors usually consists of a sintered ceramic fabricated in a variety of shapes and sizes from a mixture of oxides chosen from Mn, Co, Ni, Cu, Fe and etc….By varying the composition and the size of the semi-conducting elements, resistance values between 100 and 10⁶ ohms at room temperature can be achieved with temperature coefficients lying between -2% to -6.5% per °C.
