ntc热敏电阻2.7KB值：3470 R/T表(温度/阻值分度参数
发布时间：2019-03-06 文章来源：敏创原创 点击次数：

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，2.7K的NTC热敏电阻即它在25℃时的阻值为2.7KΩ。
B值是材料常数，其由制成它的陶瓷材料所决定，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。此RT表的B值为：3470K@25/50。
本R/T表（阻值/温度）参数对照表：
1、标称阻值：标称阻值在25℃时为：2.7KΩ
2、阻值公差：阻值允许公差为：±1%
3、B值：在25/50℃时为：3470K
