Details

A current shunt resistor is a precision low-value resistor used to measure electric current by detecting the voltage drop across it according to Ohm's Law (V=IR). These components are essential for current sensing in power management, battery monitoring, and motor control applications. Key features include ultra-low resistance values (micro-ohms to milli-ohms), high power dissipation capabilities, and excellent temperature stability. Common applications include automotive systems, industrial motor drives, power supply units, and renewable energy systems. Choose this component for reliable current measurement with minimal circuit disruption, high accuracy, and compatibility with current-sense amplifiers like INA169 or AD8215. Available in surface-mount and through-hole packages for versatile PCB integration.
