通常情况所说的阻值即为NTC的的标称阻值,大多数情况下即25℃时的阻值,它提供了一个方便的参考点。例如,10K的NTC热敏电阻即它在25℃时的阻值为10KΩ,当然有也有些特殊的阻值是以其它温度为标准的,参见RT表说明。
另一个重要特征是“B”值。B值是材料常数,其由制成它的陶瓷材料确定,并描述在两个温度点之间的特定温度范围内的电阻(R/T)曲线的梯度。每个热敏电阻材料将具有不同的材料常数,因此具有不同的电阻与温度曲线。然后,B值将定义第一温度或基点(通常为25℃)的热敏电阻电阻值(称为T1),以及第二温度点(例如50℃,称为T2 )的热敏电阻电阻值。因此,B值将使热敏电阻材料在T1和T2的范围内保持恒定。即B:T1/T2或B:25/85,典型的NTC热敏电阻B值在约3000和约5000之间。
本R/T表(阻值/温度)参数对照表:
1、标称阻值:本表标称阻值在25℃时为:5KΩ
2、阻值公差:本表的阻值允许公差为:±1%
3、B值:本表的B值在25/50℃时为:3470K
