【应用】基于Littelfuse NTC温度传感器的线性化精确测温方案
Littelfuse是一家全球性的公司,可提供客观、全面和个性化的客户解决方案。2017年Littelfuse收购了世界一流的热敏电阻制造商U.S.Sensor,拓展了温度传感器市场。本文选择Littelfuse NTC温度传感器,通过设计合理的驱动电路实现NTC测温的线性化,并实现±0.1℃的精确温度测量
【应用】低成本NTC热敏电阻KT103J2在PCR仪上的应用,精度高达0.2℃
PCR仪是用于基因扩增的仪器,最核心的部分是温度控制,温度控制是否精确直接决定了实验成败。而大多数温度传感器在精度、成本、体积、封装、可靠性方面不能很好的满足PCR仪应用。Littelfuse公司的NTC热敏电阻KT103J2,提供高精度,低成本,小体积温度传感器解决方案,帮助PCR仪温控系统成功。
【经验】如何巧用热敏电阻的耗散系数δ来选择功率模块?
温升是决定器件是否适合使用的重要条件之一。热敏电阻的电流规格根据电路具体应用选择,但是工作时的温升与热耗散系数(mW/℃)紧密相关。
