               PTC熱敏電阻的分類

     按照居里溫度分類   

    PTC熱敏電阻根據(jù)居里溫度的不同分為高居里溫度PTC熱敏電阻和低居里溫度PTC熱敏電阻。

    習(xí)慣上將居里溫度高于120℃的PTC熱敏電阻稱為高居里溫度PTC熱敏電阻；

   居里溫度低于120℃的PTC熱敏電阻稱為低居里溫度PTC熱敏電阻。

     按照應(yīng)用用途分類   

                                          ?  恒溫加熱用PTC熱敏電阻
                                          ?  低電壓加熱PTC熱敏電阻
                                          ?  空氣加熱用PTC熱敏電阻
                                          ?  過流保護(hù)用PTC熱敏電阻
                                          ?  過熱保護(hù)用PTC熱敏電阻
                                          ?  液體加熱用PTC熱敏電阻
                                          ?  延時啟動用PTC熱敏電阻

     按照結(jié)構(gòu)特點分類   

                                               金屬外殼型PTC熱敏電阻
                                               外加絕緣層PTC熱敏電阻
                                               焊接包封型PTC熱敏電阻
                                               粘膠裝配型PTC熱敏電阻
