The CSO104-338T1 is a current sense resistor manufactured by Vishay. Current sense resistors are low-value resistors used to measure current flowing through a circuit. By measuring the voltage drop across the resistor (according to Ohm's Law: V = IR), the current can be accurately determined. They are widely used in power supplies, motor control, and battery management systems for overcurrent protection and precise current regulation.
