With Kelvin 4-terminal connection and TCR down to 35 ppm, Vishay Dale WSK1206...18 High Power SMT Power Metal Strip® current sense resistor reduces system errors while eliminating need for system calibration during manufacturing or in field. Solid metal nickel-chrome or manganese-copper resistive element with TCR <20 ppm/°C results in pulse-tolerant, tight-tolerance (0.1%, 0.5%, and 1.0%) resistor. Resistance values for this all-welded series range from 0.01–0.05 Ω.
