贴片合金采样电阻选型阻值大全

 合金采样电阻也称呼取样电阻,大电流采样电阻,主要优点是功率大,可耐大电流冲击,散热快,小阻值。   

大多数工程师在选型合金采样电阻的时候都是参照国际标准阻值来选型,殊不知合金采样电阻开出来的阻值大部分都不是按照标准阻值的。

下面分别介绍几种封装的合金采样电阻阻值,合金电阻一般常用的封装有:0805,1206,2512等。

0805封装合金电阻阻值:

0.001Ω,0.002Ω,0.003Ω,0.004Ω,0.005Ω,0.006Ω,0.007Ω,0.010Ω,0.015Ω,0.020Ω,0.025Ω,0.030Ω

1206封装合金电阻阻值:

0.001Ω,0.002Ω,0.003Ω,0.004Ω,0.005Ω,0.006Ω,0.007Ω,0.008Ω,0.010Ω,0.012Ω,0.013Ω,0.015Ω,0.018Ω,0.020Ω,0.025Ω,0.030Ω,0.040Ω,0.039Ω,0.050Ω,0.060Ω,0.070Ω,0.080Ω,0.090Ω,0.1Ω

2512封装合金电阻阻值:

0.0005,0.0015Ω,0.001Ω,0.002Ω,0.0025Ω,0.003Ω,0.004Ω,0.005Ω,0.006Ω,0.007Ω,0.008Ω,0.010Ω,0.012Ω,0.013Ω,0.015Ω,0.016Ω,0.018Ω,0.020Ω,0.025Ω,0.030Ω,0.040Ω,0.039Ω,0.050Ω,0.060Ω,0.070Ω,0.080Ω,0.090Ω,0.1Ω,0.12Ω,0.13Ω,0.15Ω,0.18Ω,0.2Ω,0.22Ω,0.24Ω,0.27Ω,0.28Ω,0.3Ω,0.33Ω,0.4Ω,0.5Ω,0.75Ω,0.91Ω

以上阻值基本就是合金电阻能做的阻值范围。
