LED器件中作为发光层的半导体PN接合面会发热，该温度称为接合温度。流过LED的电流变大时亮度将会提高，发热量也会随之增加，从而接合温度将会变高，寿命将会缩短。此外，若接合温度过低时，发光效率将会下降，从而亮度将会降低。为此，为了发挥LED的最大效率，需要以最佳温度进行工作。通过将NTC热敏电阻嵌入电路，并与LED进行热耦合后，便可作为简易温度保护电路进行工作。若与最佳工作温度存在偏差，则会以NTC热敏电阻的电阻变化形式表现出来，此时将会对流过LED的电流进行补偿。最终将会在降低LED电力损耗的同时实现长寿命化。

为此硕凯电子推出一款测温型热敏电阻SN0402X103F3450FB，可用于做精确温度检测。采用绿色环保的0402封装，无极性区分。可过卤素测试，有可靠性高、机械应力强、耐环境性、耐变换电阻等优异性能。

阻值R值为10KΩ，R值误差精度可达±1%，B值为3450K（25/50°C）。还具有较高的耐环境适应性，工作温度范围为-40～+125℃。

产品特点：

● R值（25℃）：10KΩ

● R值误差：±1%

● B值（25/50℃）：3450K±1%

● 热时间常数：3S

● 额定功率：100(mW)

● 工作温度范围：-40～+125℃

典型应用：

● 智能手机/平板

● 电池保护板

● LED照明系统

● 微控制器
