低电阻表面贴装电流分流器

资料介绍
摘要: 超低电阻表面安装电流检测电阻像理想的包。物理设计,皮带的金属,似乎理想,提供可能的最低电感。往往这些电阻需要某种形式的电阻电容筛选以限制开关噪声峰值。问题是分流器的时间常数是除以回路电阻的包电感。因此,低分流电阻、 越长衰变倍。

APPLICATION NOTE 908
Ultra-Low Resistance Surface Mount Current Shunts

Abstract: Ultra-low resistance surface mount current-sense resistors seem like the ideal package. The physical
design, a strap of metal, seems ideal, offering the lowest inductance possible. Too often these resistors need
some kind of resistor capacitor filter to limit the switching noise spikes. The problem is that the time constant
for the shunt is the package inductance divided by the circuit resistance. Consequently, the lower the shunt
resistance, the longer the decay times.
