NTC 500K±3% B值4050 RT阻值表(温度/阻值对照表)
时间:2019-01-22 来源:敏创电子 编辑:热敏电阻厂家 浏览:次
RT表即为平常所说的NTC热敏电阻温度传感器RT关系表,主要反映NTC在不同温度所对应的不同电阻值,其正确的参数在软件开发中有非常重要的作用。标准的RT表一般包括几个主要参数:①标称阻值;②B值;③±范围内允许的公差阻值
本表为500K±3% B值=4050K NTC R/T阻值表,标称阻值在25℃时为500kΩ,B值为4050k,允许偏差精度为±3%,详细参数见下表。
标称阻值:500k kΩ @25℃;公差精度: + / -3%
B值 :4050K@25/50℃;B值精度:+ / - 1%
