The LVK20R039FER is a four-terminal precision current-sense resistor from the LVK series, designed for accurate measurement of current flow. It offers a precise resistance of 0.039Ω with a 1% tolerance and a power rating of 0.75W at 70°C. This 2010 size component features an excellent Temperature Coefficient of Resistance (TCR) of 50 ppm/°C and can handle a maximum over-current of 23A. The four-terminal Kelvin configuration isolates the current and voltage sensing paths, eliminating terminal resistance effects for more accurate measurements. Made with a durable, anti-corrosive metal alloy, this resistor is ideal for applications requiring reliable performance in harsh environments, such as power management and industrial controls.
