WebWhat size shunt resistor should be used? The size of the shunt resister depends on the maximum current rating. It is calculated by the voltage drop at the maximum current rating. Let say a shunt resistor is designed for maximum current 100 A and voltage drop 50 mV. Typically, the voltage drop at maximum current is 50 mV, 75 mV, or 100 mV. WebThe PCB layout gives a general sense of the size of the layout. A 1206 resistor footprint was used for the 0.25-W, 1-mΩ shunt. Notice that the voltage across the shunt is measured directly at the ends of the resistor. This is called a Kelvin connection and eliminates errors from parasitic resistance in the current path.
