【选型】光模块PCB板温度监控推荐国产贴片NTC热敏电阻，全温检测精度达±0.1℃
光模块(optical module)光电器件包括发射TOSA和接收ROSA两部分组成，其中发射TOSA激光二极管（LD）和接收ROSA雪崩二极管（APD）对环境温度变化非常敏感，光电转化和电光转化均是在腔体内实现的，为监控和控制光模块腔体内的温度，一般是通过NTC热敏电阻监控PCB板工作温度间接实现的，NTC热敏电阻选型因素参考如下：
1、 高精度：需要阻值和B值精度均要很高，精度误差一般需要±1%；
2、 小尺寸：因为光模块的空间结构非常有限，需要选择小体积的NTC，建议选择0402封装；
针对如上设计需求，推荐硕凯电子NTC热敏电阻SN0402X103F3435FA，采用成熟厚膜制造工艺，在陶瓷基板上印刷一层较厚（30μm）的NTC陶瓷材料，再配以特殊的电极结构进行烧结而成，在25℃常温阻值是10kΩ±1%，B(25/85℃)=3435k±1%，工作温度范围-40℃~125℃，相关电性参数如下图1所示：
图1：硕凯电子NTC热敏电阻SN0402X103F3435FA典型电性参数
推荐理由总结如下：
1、高精度：可以进行阻值修正，全温度范围温度检测精度可以做到±0.1℃；
2、小型化：采用0402表面贴装，体积小，可节省PCB占板空间；
3、高稳定：厚膜结构焊接造成的热冲击十分小，稳定性高；
4、高安全性：当热崩溃发生时，会安全断开，产品不会有过热情况发生；
5、特殊的端部电极结构，可以很好的释放热冲击和电路板弯曲造成的机械应力，弯曲测试对产品的性能影响很小；
6、市场上有成熟的设计应用，产品性能得到验证。
