【经验】解析PPTC与热敏电阻的关系与特点
大家都知道PPTC,但热敏电阻很多人就比较疑惑了,实际上,根据中国语言文字称呼不同,自恢复保险丝、聚合物开关、过流保护片等,这些也都称为PTC热敏电阻。优恩半导体公司将介绍PPTC与热敏电阻的关系与特点,具体内容如下:
图 1
PPTC是高分子聚合物正温热敏电阻,归属线性元器件的一种,是由特殊材料半导体制作的电阻,由于对温度比较灵敏,其电阻会随着温度的变化而变化,目前常见的PTC有两种,PPTC聚合物自恢复保险丝与CPTC陶瓷保险丝。
两者虽然都属于PTC,有着维持电流作用,但在初始阻值以及响应速度、尺寸大小方面却有差别,PPTC自恢复保险丝比陶瓷保险丝尺寸更小、阻值更低、响应速度也更快,因此,在选择上,PPTC自恢复保险丝使用范围要比陶瓷保险丝广。
PPTC自恢复保险丝特点:
●电阻温度高,比金属大十至百倍,对于温度变化更灵敏;
●工作可控温度范围广,对于常温器件、高温器件以及低温器件都能适用;
●可持续工作时间长,使用寿命;
●小体积,对于其他温度测量器件无法测量的温度都能测量到;
●应用及结构简单,在使用上很方便,电阻值可在0.1~100kΩ间任意选择,还能对其进行加工生产;
●性能稳定,过载能力强。
PPTC自恢复保险丝应用范围广泛,可应用于家用电器、汽车电子、工业电子、电源适配器、通讯、宇航等各个领域,是一种过流保护元器件。

【经验】贴片式PPTC的使用注意事项及应用范围
贴片式PPTC是一种片状形式的小型保险丝,单从肉眼上看与普通电阻并无一二,但实际它具备的特性要比普通电阻更具优势。其具备较强的分段能力,当规定电流与额定分断电流之间的电流流过时,PPTC不会熔断,也不会对其它元件造成干扰。

解析PPTC特性和选型
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。
