PTC热敏电阻的分类

     按照居里温度分类   

    PTC热敏电阻根据居里温度的不同分为高居里温度PTC热敏电阻和低居里温度PTC热敏电阻。

    习惯上将居里温度高于120℃的PTC热敏电阻称为高居里温度PTC热敏电阻；

   居里温度低于120℃的PTC热敏电阻称为低居里温度PTC热敏电阻。

     按照应用用途分类   

                                          ?  恒温加热用PTC热敏电阻
                                          ?  低电压加热PTC热敏电阻
                                          ?  空气加热用PTC热敏电阻
                                          ?  过流保护用PTC热敏电阻
