本文中，AEM科技介绍了可恢复保险丝工作原理，两者的差异性，一次性保险丝和可恢复保险丝两种产品有共同点和差异的存在，使得这两类产品能够在市场上长期共存，各得其所。

可恢复保险丝工作原理

可恢复保险丝本质上是正温度系数热敏电阻，它是通过PTC材料的电阻值对温度的正相关及在居里温度点时的突变而起到电路保护作用的，这一点原理跟保险丝完全不同。

一次性保险丝和可恢复保险丝的异同

一次性保险丝和可恢复保险丝两种产品的相同点：它们都可用来做电路的过电流保护，其使用的不少领域和场合有类似，还有一部分场合这两种产品都可以使用，还可以互相替换，例如在过流保护要求不太高的电池保护应用中这两类产品都能各领风骚；在对某些IC等重要器件保护应用中，或电源的输入/输出端就只有一次性保险丝才有可能胜任其保护功能，这些部位对阻抗要求也较高；而一些必须避免因过热而烧坏产品的场合，或者是经常需要热插拔操作的接口过流保护，则是PTC的最佳用武之地；

然而在更大多数的场合里，这两类产品还是有很多很多的差异，甚至根本不可能互相替代，它们的主要区别或差异可以通过下表内容来体现：

由于有共同点和差异的存在，使得这两类产品能够在市场上长期共存，各得其所。

【技术】解析自恢复保险丝与一次性保险丝比较

关于电路过流保护，主要的方式有：一次性保险丝，自恢复保险丝，断路器，继电器，部分对保护要求不高的场合会使用保险电阻，开机浪涌电流防护会考虑功率NTC，甚至部分IC会内部集成过流保护功能。本文顺络解析自恢复保险丝与一次性保险丝比较。

一次性保险丝和可恢复保险丝有什么区别？

一次性保险丝一般由三部分组成：主体是低熔点的金属丝或者金属薄片制成的熔体，是熔断器核心；电极端头连接电路与熔体，具良好导电性；支架，固定熔体并使三部分成为刚性的整体。两种保险丝都可用来做电路的过电流保护，其使用的不少领域和场合有类似，有一部分场合这两种产品都可以使用，还可以互相替换。例如在过流保护要求不太高的电池保护应用中这两类产品都能各领风骚。在对某些IC等重要器件保护应用中，或电源的输入/输出端就只有一次性保险丝才有可能胜任其保护功能，这些部位对阻抗要求也较高。另外在一些一旦发生故障就必须停机检修排除故障的场合，也要求使用一次性保险丝。而一些必须避免因过热而烧坏产品的场合，经常需要热插拔操作的接口过流保护，可简易排除故障，以及非器件故障导致的暂时性过电流的电路保护则应该选择可恢复保险丝。
