USB端口因频繁插拔、松动等原因会受到浪涌电流的威胁。在USB 3.0的规范中，明确使用限电流组件作为电源端之保护。竞沃电子为USB端口提供专业的电路保护解决方案。

PPTC在USB 3.0 端口中的保护应用：

USB 3.0 端口保护电路如下图：

如上图所示，在USB的VBUS线路上串联了一个PPTC元件，与保险丝相似的是，PPTC元件有助于保护电路免受电流的损坏。它与保险丝的不同之处在于电路断电情况下，PPTC元件可自行复位并消除故障。除了这项自复功能之外，PPTC元件在USB应用中拥有很多关键性的设计优点，其中包括低电阻、快速动作时间、低的功率损耗和固有的抗误特性。

在USB 3.0应用中，PPTC组件与低压半导体组件的比较，在价格、阻值、最大故障电流能量及静电敏感度等方面均更具优势。

使用保险丝时注意事项：

1、选型时根据产品工作时的最高直流电压选择相应参数的保险丝，保险丝工作温度会达到70-80℃，选择保险丝时要注意在这个温度的I-Hold电流满足产品需求。

2、保险丝下方铺地提高散热效果；

3、布局走线时将保险丝靠近接口位置；

采用PPTC自恢复保险丝，可以保证超温、过流时及时保护又不需要更换保险丝、同时也不会出现保护后再次接通故障电路的问题。

东莞市竞沃电子科技有限公司主营产品包括自恢复保险丝、一次性保险丝、EV熔断器、瞬态电压抑制器、静电抑制器、精密电阻等线路元器件，产品应用于通讯设备及监控，汽车电子，工业及家电，锂电池及电池组，电脑及其周边产品，消费类及多媒体电子设备，电动玩具等行业。

竞沃电子推出可支持USB 3.0 端口应用系列保险丝包括如下系列：PSML200、NSML260、USML750、NSML380L、MSML300。主要参数如下表：

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。

陶瓷管保险丝与玻璃管保险丝可以通用吗？

陶瓷管保险丝与玻璃管保险丝不可以通用。陶瓷保险丝的过电流量要高于玻璃管的，陶瓷内的石英砂有降温灭弧的作用，电流量超过标称容量时，不可用玻璃管的代替陶瓷的，反之陶瓷代替玻璃管的也会失去保护作用。

方形保险丝有哪些优点？

1、相对于其它保险丝器件来说，方形保险丝体积在众多保险丝中体积也算是小的，脚距为5.08mm，占用的线路板空间相对较小，和传统的保险丝相比，缩小了很多空间。 2、方性保险丝除开两个引线以外，表面全是塑料材料制作而成，所以表面绝缘，具有阻燃和绝缘的作用。 3、方形保险丝比较优势的特点就是分段能力，目前竞沃的方形保险丝的分断能力是6.3A/350V，和力特的392微型保险丝比起来，稍微有点差别，但因为是国产保险丝，性价比还是很高的。
