50k热敏电阻阻值表
50k热敏电阻阻值表热敏电阻是一种温度敏感的电阻器件，其电阻值随温度的变化而变化。
50k热敏电阻的电阻值在不同温度下有不同的取值，下面是50k 热敏电阻在一定温度范围内的阻值表。
温度（摄氏度）阻值（千欧姆）-40 1.9-30 2.2-20 2.5-10 2.90 3.410 4.020 4.730 5.640 6.850 8.260 10.070 12.280 15.090 18.2100 22.0随着温度的升高，50k热敏电阻的阻值也会增加。
可以看到在-40摄氏度时，50k热敏电阻的阻值最小，为1.9千欧姆；而在100摄氏度时，阻值最大，为22.0千欧姆。
这种温度与阻值之间的关系可以用一个特定的数学模型来描述，该模型的具体形式可以参考相关的热敏电阻的数据手册。
热敏电阻广泛应用于温度测量、温度控制等领域。
由于其阻值与温度呈正相关关系，因此可以通过测量热敏电阻的阻值来推算出被测量物体的温度。
这种测温原理简单可靠，被广泛应用于各种温度测量场合。
50k热敏电阻的阻值表提供了在一定温度范围内的阻值参考，可以用于工程设计和实际应用中。
在实际应用中，我们可以根据需要选择合适的热敏电阻型号和使用温度范围，以满足具体的测温要求。
同时，还可以根据50k热敏电阻的阻值与温度的关系，进行温度的插值计算，得到非标准温度下的阻值数据。
需要注意的是，50k热敏电阻的阻值表中的数据是经过实验测量得到的，具有一定的误差。
在实际应用中，我们应该根据具体情况进行校准和修正，以提高测温的准确性和可靠性。
50k热敏电阻阻值表提供了在一定温度范围内的阻值参考，可以用于热敏电阻的选择、测温数据的推算等应用。
