About this product
A 2512 SMD alloy power shunt resistor rated at 1 W with a 0.010 Ohm value, marked R010. Its very low resistance produces a small voltage drop per ampere, making it suitable for measuring high currents in battery packs, motor controllers and power supply outputs.

Frequently asked questions
What current can this 0.010 Ohm shunt handle at 1 W?
At 0.010 Ohm, 1 W corresponds to about 10 A (square root of 1 W divided by 0.010 Ohm). Derate this in practice, because the rated power depends on board heating and ambient temperature.
What voltage signal does it produce for measurement?
The voltage drop equals current times resistance. For example, 10 A through 0.010 Ohm produces 0.1 V, which is a readable signal for an amplifier and ADC.
