The LVK20R020DER is a high-precision, four-terminal current sense resistor designed for accurate current monitoring. It features a resistance value of 0.020 ohms with a tight tolerance of 0.5% and a low Temperature Coefficient of Resistance (TCR) of 50 ppm/°C. This 2010-size component has a power rating of 0.75W at 70°C and can handle a maximum current of 23A. The Kelvin configuration isolates the current and voltage sensing terminals, which eliminates measurement errors caused by terminal resistance, making it ideal for applications like power management, motor controls, and battery systems.
