汽车电子电路保护设计
汽车电子是当前一个热门开发领域，中国汽车市场的蓬勃发展为本土汽车电子产业带来了新的机遇。越来越多的企业纷纷加大了在汽车电子产品上的投入力度，包括ECU、ABS、DVD、GPS、HVAC、CAN BUS等在内的大量汽车电子产品的本土化设计制造厂商如雨后春笋般冒升，这也为从事电路保护设计的电子元器件厂商开辟出一片崭新的天地。
安全、可靠性至关重要
保险丝是一类被动无源器件，类似一个开关。当产品出现故障或者发生意外时，需要保险丝能够安全地在电源部分实现有效的断开，不产生明烟/明火，更不能危及操作人员的生命安全。因此，无论任何电子产品，通常无一例外都要配置保险丝，它也是电子产品安全的保障。
对于保险丝而言，最主要的参考指标就是安全与可靠性，即在正常工作时绝对不可以断开，当后级的故障发生时则必须马上断开。保险丝只有两个工作状态：导通或者断开。要保证整个系统的安全与可靠，保险丝本身必须首先要满足这两点。良好的保险丝设计应用必不可少，也是一门精巧的学问。
电路设计人员在选择保险丝时，应主要从两个方面来考虑：静态和动态。静态是指电压、电流、环境温度、尺寸、失效电流等；动态则指的是熔断时间、熔化热能值等，这些都是保险丝产品选择设计的关键点。其次，通过保险丝的理论计算之后，还需要再结合现场进行测试验证，借助可靠性分析最终达成理想的设计方案。

创新型汽车电路保护设计
汽车里面的电路保护无处不在，尤其是现在汽车车身采用了越来越多的智能化电子设备，把以前纯粹的汽车机械变成了有灵魂的“跑动的机器人”。对于电子化产品来说，安全是首要的，汽车电路中的保险丝也因此而变得集成化和小型化。
在汽车电子的开发中，几乎每一个用电设备都需要一个保险丝，通常称作线缆保护。保险丝的主要作用是限制电流的增加，当出现意外(例如车祸造成的电源短路故障)，这时产生的大电流就需要保险丝马上把主电源切断，以避免发生进一步的危险。传统的汽车线缆保险丝的防护架构为多极且分层式，但最次一级的电子设备出现故障时，则仅仅是出现故障的单元保险丝断掉，而不会影响到上一级的电路。但是在汽车改装的过程中，例如在外部加了一个大功率音响时，其取电来自于车身电瓶，如果保险丝使用不当，在需要断开的时候没有断开，就会因为这些小故障影响到整车系统的可靠性，造成保险丝的错误动作，因此，良好的保险丝设计与选择就显得尤其重要。

【技术】浅谈汽车电子保险丝的类别及更换方法
保险丝，也被叫做电流保险丝、熔断器，主要起的是限流作用，本文优恩半导体讲为我们介绍汽车电子保险丝的类别及更换方法。对于汽车电子来说，其内部使用的保险丝就是这么重要，在汽车电路中，其内部结构非常复杂，这些系统用电设备都是用不同的电线连接起来。
如何根据实际电路来选择保险丝或PTC
使用保险丝对于故障诊断非常有用，它能够帮助设备的设计者和用户查找过流故障的根源。而本文针对如何根据具体应用选择最佳过流电路保护装置（PTC或保险丝）有详细的描述。

如何选择保险丝的额定电流参数？
根据电路的额定工作电流来选择保险丝的额定电流即额定电流=工作电流/0.75。当计算出的值不是规格书中常见的额定电流时，应选择最临近额定值的较高值。
