Claim 0:
1. A shunt resistor module, comprising:
a shunt resistor; and
a printed circuit board (PCB) substrate, wherein the shunt resistor is configured to be directly fixed to the PCB substrate,
wherein the shunt resistor includes:
a resistor unit having a predetermined resistance;
first and second plate-shaped terminal units extending from respective sides of the resistor unit; and
first and second voltage measurement lead pins including respective perpendicular portions protruding perpendicular to the first and second terminal units, respectively, and respective first bent portions parallel to the first and second terminal units, respectively,
wherein the PCB substrate includes an assembly guide portion including first and second cuts cut into the PCB substrate from an outermost side of the PCB substrate by a predetermined depth, each cut having a cut width corresponding to a thickness of a corresponding voltage measurement lead pin, and
wherein the first and second voltage measurement lead pins are shaped to fit through the first and second cuts of the assembly guide portion so that the resistor unit and the first and second terminal units are positioned on a front surface of the PCB substrate and the first bent portions of the voltage measurement lead pins are caught at a rear surface of the PCB substrate.
