NTC热敏电阻温度传感器5K和10K、50K、100K的区别

发布时间:2019-03-07    文章来源:敏创原创    点击次数:


NTC热敏电阻温度传感器5K和10K的主要区别在于它们的阻值上的不,5K在25℃时的标称阻值为5KΩ,10K在25℃时的标称阻值为10KΩ,50K在25℃时的标称阻值为50KΩ,100K的25℃时的标称阻值为100KΩ。

 
5K和10K、50K的B值曲线也不同,5K的常用B值有:3375k、3470K、3950K;10K的B值曲线有3700k、3935k、3380k、3450k、3550k、3600k、3977k、3950k。50K的B值曲线有3899K、3910K、3405K、4050K。50K的B值曲线有:3920K、3900K、3950K、3990K、4020K、4050K、4200K。
 
使用范围:
5K的热敏电阻特别适用于一次性和永久性医疗产品使用,以及能源管理系统,电器,工业设备和汽车应用。虽然适用温度范围在-80°C至+ 150°C,但在不超过105°C的温度下可获得最佳稳定性。
10K和100K的NTC热敏电阻则广泛应用于温度检测,测量,检测,指示器,监测,测量,控制,校准和补偿等,适用于暖通空调和白色家电,汽车,电池组应用。使用范围更广也更经济。

 
下表对比NTC 5K和10K、50K、100K热敏电阻在B值同样为3950k下的不同阻值差异。
