TLC PTC自复式器件可防护过电流浪涌及过热的故障。PPTC热敏电阻可在故障条件下限制危险的大电流通过。但是它不同于只能使用一次就必须更换的传统保险丝，PPTC热敏电阻在故障排除和电路电源断开之后能够自动复位，进而减少了保固、服务和维修费用。 PPTC电路保护器件是由高分子聚合物掺加导体所制成的。如图1所示，在正常温度下聚合物呈现结晶状并将导体束缚成紧密的导电链，从而构成一个低阻抗的连接。当大电流通过或周围环境温度升高导致器件温度高于动作温度时，聚合物融化体积膨胀从而使导体变成无规律排列，并导致阻抗迅速提高。

PPTC动作原理

PPTC器件动作原理是一种能量的平衡，如图2所示：当电流流过PPTC器件时，由于I²R的关系会产生热量，而产生的热量便会全部或部分散发至环境中，没有散发出去的便会提高PPTC器件的温度。在图2的Point 1时温度较低，产生的热量和散发的热量达到平衡，但是当流过的电流较多或是环境温度较高时，会产生较高的热量，而提高PPTC器件的温度，当电流或环境温度的增加并不显著，PPTC器件所产生的热量可以散发至环境中而在Point 2达到平衡。当电流或环境温度再提高时，PPTC器件会达到一个较高的温度，如图Point 3所示。若此时电流或环境温度继续增加，产生的热量便会大于散发出去的，使得PPTC器件温度速增，在此阶段，很小的温度变化就会造成阻值大幅度提高，这现象可由图上的Point 3及Point 4看出。这时PPTC器件正处于动作的保护状态，阻抗的增加便限制了电流的通过，而保护设备免于损坏。如上所述PPTC热敏电阻在环境温度升高时，其阻值亦会随之增加，从而达到Point 4的高阻抗状态，并不需外加电流，当温度下降后PPTC就以热敏电阻的特性回复到低阻抗状态。此种现象可用来温度感应控制。

保持和动作电流作为温度函数的示例

图3说明了作为温度函数的PPTC器件的保持和动作电流行为。可以为每个可用器件定义一条这样的曲线。A区说明了PPTC器件将动作（转到高阻值状态）以保护电路时的电流和温度的组合。B区说明了PPTC器件将允许电路正常操作的电流和温度的组合。在C区，此器件可能动作或保持在低电阻状态（这取决于单个器件的电阻）。

聚合物PPTC在不同温度下的动作特性

图4显示了在0℃和75℃环境下的静止空气中聚合物PTC器件的一对典型运行曲线。这些曲线是不同的，因为需要动作器件的热量来自电气I2R加热和器件环境。75℃时环境的热量输入要比0℃的热量输入大得多，因此动作所需要的附加I2R相对较少，造成在给定的动作时间内的比较低的动作电流（或在给定的动作电流下动作更快）。

动作后器件阻值恢复特性

图5显示了动作和随后允许冷却的PPTC器件的典型行为。在此图中，我们可以清楚地看到，即使在若干小时以后，器件电阻依然大于初始电阻。电阻的减降过程会延续一段较长时间，最终电阻才接近初始电阻。然而，这个时间可以是几天，几个月或几年，但是为了动作而指望器件电阻恢复到原来的值是不实际的。所以选择PPTC器件时，当决定保持电流时必须考虑R1MAX的值，即动作并恢复1小时之后最大阻值。

什么是自恢复保险丝？

自恢复保险丝是一种过流电子保护元件，采用高分子有机聚合物在高压、高温，硫化反应的条件下，搀加导电粒子材料后，经过特殊的工艺加工而成。自恢复保险丝（PPTC：高分子自恢复保险丝）是一种正温度系数聚合物热敏电阻，作过流保护用，可代替电流保险丝。电路正常工作时它的阻值很小（压降很小），当电路出现过流使它温度升高时，阻值急剧增大几个数量级，使电路中的电流减小到安全值以下，从而使后面的电路得到保护，过流消失后自动恢复为低阻值。传统保险丝过流保护，仅能保护一次，烧断了需更换，而自恢复保险丝具有过流过热保护，自动恢复双重功能。在习惯上把 PPTC(PolyerPositiveTemperature Coefficent)也叫自恢复保险丝。其效果与开关元件类似，只是响应速度较慢。

过流保护器件自恢复保险丝PPTC的优点是什么？

自恢复保险丝优点：自恢复保险丝常温零功率电阻可以作得很小，大电流产品只有几个毫欧姆，在路功耗较小，可以忽略不计、体积相对较小。自恢复保险丝可串联在易损电路内作过流保护、温度保险丝用，阻值突变速度快，在几个ms数量级，热容小，恢复时间短，耐冲击，可循环保护达8000次之多。自恢复保险丝可以作过温度保险丝用，因此在电路中在一定程度上体现出了温度保险丝性能和温度保险丝作用。达到在电路中实现过流保护和过温保护的双重保护功能。
