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。
