FEATURES
Current shunt resistors are low resistance precision resistors
used to measure AC or DC electrical currents by the voltage
drop those currents create across the resistance. Sometimes
called an ammeter shunt, it is a type of current sensor.
2 or 4 ports available
Tight Tolerance of
±1%
and Tight TCR of
±100ppm
