NTC 2300K B值4537 RT阻值表(NTC温度/阻值对照表)

时间:2019-01-25 来源:敏创电子编辑:热敏电阻厂家浏览:


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230K±3% B值=4537K NTC R/T阻值表,标称阻值在25℃时为230kΩ,B值为4537,允许偏差精度为±3%,详细参数见下表。


标称阻值:230 @25℃;公差精度: + / -3%
B值 :437[email protected]/200℃;B值精度:+ / - 1%
