PCB Mount EB Weld Shunt

Our special designed EB (electron beam) weld shunt resistor can be easily mounted on the PCB. The mount points pass the secondary current, which is proportional to the primary current, similar to the function of a mini current transformer. For different applications, the PCB mount points can be replaced by lead wires. Due to our high power electron beam welding and high-speed stamping technology, we can manufacture EBW manganin shunt resistors of wide-range rated current and make quick delivery for large-scale production. We can also design customized shunt of complicated structures and provide samples within a couple of days.
