众所周知,PPTC自恢复保险丝是使用极为广泛的一种过流保护元器件,在一些笔记本电脑、汽车电子、以及变压器、工业控制设备,当然,也包括一些通讯接口,PPTC都能起到过电流和过温保护的作用。



而RS-485正是目前市场中比较流行的一款通讯接口,在通信速率100Kbps时,其通讯距离可长达1200m以上,并且具备高的信噪比、好把控以及价格低等优势,使其成为畅销型通讯接口方式之一。


由于RS-485通讯传输线是在户外,它自身的工作电压也只有5V,因此,特别容易受到静电及雷电的损害,故如何解决ESD静电放电及雷击浪涌,自然也是让众多工程师困扰的问题。


在优恩工程师通过不断测试及ESD静电整改过程中,针对其过流保护器件,推荐产品为自恢复保险丝,简称PPTC。


自恢复保险丝由聚合物基体及使其导电的碳黑粒子组成,是一种正温度系数聚合物热敏电阻,在RS-485通讯接口应用中可采用阻值为1.35Ω至6.5Ω,不动作电流为100mA至200mA的PPTC。


PPTC自恢复保险丝从很大一种程度上看,是可以替代电流保险丝的,在流过正常工作电流时,它的阻值很小,可视一颗导线,但当电路流过的电流是正常工作电流的2倍或2倍以上时,它的阻值就会变大,进而起到限流防护作用,当电源断开,过电流消失后,保险丝又会恢复到出厂的低阻值。

【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。
