How To Choose The Right Precision Shunt Resistor For Reliable Current Measurement
To choose the right precision shunt resistor for reliable current measurement, confirm four things together: the resistance value is appropriate for both signal level and power loss, the tolerance and TCR fit the real temperature range, the layout supports true Kelvin sensing, and the part has enough thermal and long-term stability margin for the actual load profile. When those checks are made together, the shunt resistor becomes a reliable measurement component rather than just a low-ohmic part on the BOM.
