代码标示法一般适用于小体积的贴片元件。因受元件表面积的限制，不便采用直标
法，只能在元件正面印上一个或几个简单的符号（字母、数字或几何图形），代码标示法
又分为字母（或数字）标示法和图形Байду номын сангаас示法。
LITTLEFUSE公司的标识。为压缩篇幅，没有列出其型号、代码及主要参数对照表，而 直接从上例中的表6来查3位数字代码与保持电流的对应关系。表6大部分是4位数字代码， 查找时去掉表中代码最前面的“0”，按3位数字代码来处理即可。如图14的PPTC自恢复保 险丝，代码为“260”，由表6的代码“0260”即可查得保持电流为2.60A。又如图15的贴 片，代码为“030”，但表6中无代码“0030”一项，这时我们可以根据表6数据的规律判断 出贴片“030”的保持电流为0.30A。在这里须特别指出的是，因为厂家、型号的区别，所 以只能从表6来查3位数字代码与其保持电流、触发电流的对应关系，而不能查3位数字代 码与其型号及最大电压的对应关系。否则将出错!

贴片自恢复保险丝测试指南
贴片自恢复保险丝测试指南贴片自恢复保险丝测试指南一：测试流程如下：1. 初始内阻Rimin 测量：拆包装，拿出保险丝，测量保险丝的内阻；2. 焊接：将保险丝通过回流焊焊接在PCB上，PCB上连接有引线，便于进行电性能测试（如上图所示）；3. 保持电流Ihold测试：选用直流恒压恒流源进行测试。
将电压调节到规格书规定的电压Vmax，电流调节到规格书规定的保持电流Ihold，通电15分钟；4. 动作电流Itrip测试：选用直流恒压恒流源进行测试。
将电压调节到规格书规定的电压Vmax，电流调节到规格书规定的保持电流Itrip，通电5分钟；5. R1max测试：将动作后的保险丝放置冷却1小时，测量保险丝的内阻。
二：测试标准：1. 测试环境为25℃的室温环境，无光照、无热辐射；2. 保险丝初始内阻Rimin 需在规格书范围内；3. 保险丝在Ihold电流下保持15分钟不动作，判定为合格；4. 保险丝在Itrip电流下5分钟以内动作，判定为合格；5. 保险丝动作后内阻R1max需在规格书范围内。
三：测试过程中的常见问题附FAQ：Q：实验室只有万用表，可以对内阻进行测量吗？A：推荐使用专业的微电阻测试仪表（如Hioki 3540）进行测量，在没有微阻计的情况下可用万用表作粗略的测量。
Q：实验室没有专业电源设备，用普通的恒压恒流源进行测试可以吗？A：可以用普通的恒压恒流源进行测试。
Q：实验室没有PCB，可以直接放在桌面上进行测试吗？A：保险丝能不能起保护，本质上是保险丝吸收的热量大于释放的热量，保险丝本身的热量不断积累，达到一定程度后保险丝即会起保护。
使用PCB进行测试是对保险丝使用环境的真实摸拟。
若在木质桌面、塑料板、或毛布上面进行测试，因为不同材质的热交换不同，会影响到保险丝热量的释放，从而影响到测试的准确性。
Q：实验室没有SMT设备，可以进行手工焊接吗？A：高分子是自恢复保险丝主要的材料之一。
因高分子受热会影响到其微观状态，进而影响到保险丝的内阻。

Storage
The maximum ambient temperature shall not exceed 35°C . Storage temperatures higher than 35°C could result in the deformation of packaging materials. The maximum relative humidity recommended for storage is 75%. High humidity with high temperature can accelerate the oxidation of the solder plating on the termination and reduce the solderability of the components. Sealed vacuum foil bags with desiccant should only be opened prior to use. The products should not be stored in areas where harmful gases containing sulfur or chlorine are present.
