一、介绍

PPTCPolymer Positive Temperature Coefficent),学名:高分子聚合物正温度系数热敏电阻。PPTC主要用于电子设备的短路及超载保护,与传统保险丝相比,具有可恢复功能,故又称为自恢复保险丝



PPTC主要是由聚合树脂和导电材料所组成。在正常工作条件下,其表现出极低的电阻值,对电路性能基本上不会产生影响。


当异常电流发生或环境温度提高时,其阻值迅速提高,呈现高阻抗的状态,从而限制异常电流流过PPTC元件,此过程称为“动作”。


当故障得到排除后,PPTC元件自动恢复到低阻状态,此时电路又可以回到正常工作的状态。


二、特性

由聚乙烯(Polyethylene)及导体(主要成分为碳黑Carbon Black)所组成。在正常的操作温度下,聚乙烯紧密地将导体包裹在结晶状的结构内,而形成一条低阻抗的导电通路如图中的(1a)所示。因为阻抗相当的低,所以线路上流经PPTC组件的电流所产生的热能小,不会改变聚乙烯的晶体结构。异常电流发生,导体上所产生的热能便会将聚乙烯由结晶状变成胶状(Amorphous),如图中的(1b)所示,在此种情况下,被包裹的导体便会因聚乙烯的膨胀而分离,导致阻抗迅速提高而限制异常电流流过PTC组件。异常电流消失后,导体通路又会再度结合成为低阻抗。



三、PPTC的选型

首先要根据产品具体的工作电流、电压来选择一个适合的型号,再看产品实际的工作温度大概是多少度。


【从PPTC的特性来看】:

首先要根据产品具体的工作电流、电压来选择一个适合的型号,再看产品实际的工作温度大概是多少度。



温度越高器件开始动作的电流就越小,即当我们选用1A的参数器件开始动作,且工作环境温度达到60摄氏度时,器件的电流折减率达到70%即0.7A器件就会开始动作。故而我们选型的时候工作温度如果在一个较高的温度我们要选动作电流值更大一点的。

【PPTC可应用在】:

汽车领域各类产品电源输入端;

照明领域电源DC输入端防止电流过大影响后端电路、温度过高;

电机领域电源DC输入端防止电流电机堵转、温度过高;

3.通讯领域电源DC输入端防止大电流影响后端路等等。

四、总结

PPTC可以做到重复使用6000次以上,而且动作时间快、串联在电路中的损耗低。不仅是在电路上起到了一个保护的作用,在对于没有PPTC保护的电路上万一出现了问题烧坏的可能就是某个重要元件了,这也是变相起到了节约成本的作用。

贴片自恢复保险丝的功能是什么?

贴片自恢复保险丝正常工作时的温度相对较低,实现了平衡。当处于低电阻状态时,它不起作用。当流经贴片自恢复保险丝的电流增加或温度升高,但产生的热量和散发的热量仍然平衡时,它仍然不起作用。当电流或环境温度再次升高时,贴片自恢复保险丝将达到更高的温度。如果此时电流或环境温度继续升高,产生的热量将大于消散的热量,导致贴片自恢复保险丝的温度突然升高。

【经验】自恢复保险丝和TVS的结合使用,可防止四种情况造成的损坏

单独使用自恢复保险丝,或者与TVS二极管结合起来使用,都能防止负载电流过大、转换器出现故障、发动机激活时产生的瞬变电压以及汽车电池极性接反导致器件损坏。在选择PPTC自恢复保险丝器件时,必须考虑到最大负载电流、最高环境温度以及进入高阻抗状态所需要的时间。
