NTC热敏电阻

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
