过电流电路保护可以通过使用传统的熔断器或PTC（正温度系数）装置来实现。ptc通常用于各种电信、计算机、消费电子、电池和医疗电子产品应用，其中过电流事件很常见，并且需要自动复位。Littelfuse提供的PTC具有以下一般形式和特点，尺寸和容量各不相同：
表面安装设备：

●全系列紧凑型封装引脚
●低保持电流
●非常快的跳闸时间
●低电阻径向引线系列：

●高达600Vdc的保护装置
●非常高的保持电流
●低跳闸保持电流比
●低电阻。
电池引线系列：

●窄而低的设计
●可焊接的带状镍端子
●低电阻，延长电池运行时间如果您的应用要求超出我们的产品范围，在某些情况下，我们可以提供定制的解决方案。如需了解更多信息，请联系Littelfuse。
传统保险丝与PTCs保险丝和PTCs都是过电流保护装置，尽管每种都有其独特的工作特性和优点。理解这两种技术之间的差异，可以使选择更容易，具体取决于应用程序。最明显的区别是ptc可以自动复位，而传统的熔断器在跳闸后需要更换。在大多数类似的过电流事件后，熔丝将完全停止电流流动（在关键应用中可能需要），而PTC继续使设备工作，除非在极端情况下案例。因为它们会自动复位，许多电路设计人员在过电流事件预计会经常发生的情况下选择ptc，在这种情况下，维护低保修和服务成本、恒定的系统正常运行时间和/或用户透明度是很重要的。他们也经常被选择在电路难以接近或偏远的地方，如果保险丝更换很难。那里还有几个其他的操作特性需要考虑，以区分ptc和熔断器，并且最好在最终应用中使用之前测试和验证设备性能。
小的PTC特性聚合物（正温度系数）PTC和传统的熔丝器件都会对电路中过大电流产生的热量作出反应。保险丝熔断，中断电流，而PTC则在温度升高时限制电流，从低电阻状态变为高电阻状态。在这两种情况下，这种情况被称为“跳闸”。右边的图表显示了PTC对温度的典型响应。小型聚合物ptc主要由高密度聚乙烯和石墨混合制成。在过电流事件中，聚合物PTC会发热和膨胀，进而导致导电粒子断开接触并停止电流。过载后重置设备的一般步骤是断开电源并让设备冷却下来。
泄漏电流：当PTC处于“跳闸状态”时，它通过将电流限制在低泄漏水平来保护电路。泄漏电流的范围从额定电压下的100毫安（mA）到较低电压下的几百毫安（mA）。另一方面，熔断器在跳闸时完全中断电流，当受到过载电流时，这种开路不会导致泄漏电流。
中断额定值：PTC的额定值为额定电压下的最大短路电流，也称为“断开容量”或Imax。该故障电流水平是设备能够安全承受的最大电流，记住PTC不会实际中断电流流（见上文泄漏电流）。典型的小型PTC短路额定值为40A；或者对于电池带PTC，该值可以达到100A。实际上，保险丝确实会中断电流，以响应过载和中断额定值的范围，在额定电压下从几十安培（A）到10000安培不等。
工作电压等级：一般用途小熔丝PTC的额定电压不超过60V，而保险丝的额定电压不超过600V。
保持电流评级：保留（工作）PTC的额定电流可达14A，而保险丝的最大额定电流可超过30A。
电阻：回顾产品规格表明，同样额定值的ptc的电阻大约是保险丝的两倍（有时甚至更多）

【技术】为实现过流电路保护，选择保险丝还是PTC更好？

使用传统保险丝或是使用最新研发的自恢复PTC都可以实现过流电路保护。两者都是通过对电路中过量电流产生的发热现象做出反应从而实现保护功能。保险丝是靠熔断来断开电流的，而PTC则是依赖从低阻态变为高阻态来限制电流的大小。充分理解两种装置的性能差异会使您在选择最佳电路保护方案时做出更轻松的选择。
