自恢复保险丝是我们日常生活中非常常见的电路保护元件。如常用的空调，有一个自恢复保险丝用来控制电路板过流，过载，过热保护。自恢复保险丝由高科技高分子树脂和纳米导电颗粒经特殊工艺制成。正常情况下，导电颗粒与树脂链形成链状导电通路，自恢复保险丝的正常工作；当电路发生故障产生异常电流时，导电通路断开，自恢复保险丝电阻迅速上升，……

在自动调节加热器中的PTC热敏电阻，如果温度降低，电阻也降低，允许更多的电流通过，从而加热设备。同样，如果温度升高，电阻也会增加，从而限制通过的电流，从而冷却电阻。然后，PTC热敏电阻在相对较宽的电压范围内达到功耗实际上独立于电压的程度。这些PTC热敏电阻通常由各种形状和尺寸的陶瓷制成，由于其设计的灵活性，是提供可控加……

过流保护用PTC热敏电阻是一种能自动保护和恢复异常温度和电流的保护元件，俗称“自恢复保险丝”和“PTC过流保护器”。它可代替传统的保险丝，广泛应用于电动机、变压器、开关电源、电子线路等的过流和过热保护，过流保护采用PTC热敏电阻，通过电阻值的突变来限制整个电路的消耗，从而降低剩余电流值。传统的熔断器在线路熔断后不能自行……

PPTC resettable fuse is a positive temperature coefficient polymer thermistor. It is used for overcurrent protection and can replace current fuse. When the circuit is working normally, its resistance value is very small (the voltage drop is very small). W
