Frequently asked questions
What current can this 0.050 Ohm shunt handle at 1 W?
At 0.050 Ohm, 1 W corresponds to about 4.47 A (square root of 1 W divided by 0.050 Ohm). Operate below this level with margin, since the usable power depends on cooling.
What voltage signal does it give at 2 A?
At 2 A, the drop is 0.1 V (2 A multiplied by 0.050 Ohm). Ensure the sense circuit and amplifier are designed for this level and for the common-mode voltage of the rail.
