PTC THERMISTOR

■PTC 热敏电阻器

PTC THERMISTOR

PTC 是指正温度系数热敏电阻，它是一种典型具有温度敏感性的半导体电阻，超过一定的温度

（居里温度）时，它的电阻值随着温度的升高呈阶跃性的增高。

PTC is a positive temperature coefficient thermistor. It is a typical semiconductor resistance

with temperature sensitivity. When the temperature exceeds a certain temperature (Curie temperature), its resistance value increases with

the increase of temperature.
