NTC热敏电阻的阻值与温度对照表主要关注几个方面:温度、NTC阻值、阻值公差及B值。
NTC热敏电阻随着温度的升高而降低了电阻,并提供各种基本电阻和曲线。我们通知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称的,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。
1、阻值:本表标称阻值在25℃时为:10KΩ
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:3950K

负温度系数热敏电阻,简称为NTC热敏电阻,它的阻值随着工作温度的增加而降低。目前,因为NTC热敏电阻的几乎可以应用于对温度起作用的任何类型的设置中及它的高性价比,所以NTC热敏电阻已经成为最常用的温度传感器类型。
在采用NTC热敏电阻之前,得先搞明白NTC热敏电阻特有的阻值与温度(R/T)之间的关系。NTC热敏电阻的相对较大的负系数响应意味着即使很小的温度变化也会导致其电阻发生明显的变化,这也是NTC成为精确温度测试和控制的重要原因。
