TH0420 Reference Coaxial Current Shunt
The TH0420 is a set of precision coaxial shunts designed for high-accuracy current measurements. With ultra-low power coefficients, each set includes 12 shunts covering a wide range of nominal currents from 0.1 A to 500 A, converting them into nominal voltage outputs of 1 V or 0.5 V. These shunts are ideal for calibration labs, metrology applications, and industrial current measurement tasks where stability and precision are critical.
