Low inductance.
Low temperature coefficient.
Very low resistance value.
Resistance tolerance: ±5% (J).
Suitable for a wide range of current sensing applications.
CSR precision current sensing resistors are low-resistance components designed for current measurement and monitoring in electronic circuits. The series features low inductance, a low temperature coefficient, and milliohm-level resistance values, making it a candidate for circuit designs that measure current through the voltage drop across a sensing resistor.
For power supply circuits, power electronics, and industrial electronic systems, engineers can select a suitable CSR model according to rated power, resistance value, tolerance, and thermal design requirements. The series offers 1W, 3W, and 5W power ratings. This product description focuses exclusively on the ±5% tolerance option to support consistent product selection and purchasing specifications.

Selection note: The available resistance range varies by rated power. Confirm the resistance value against the specific model before ordering. When ambient temperature exceeds 70°C, the allowable load must be reduced according to the product derating curve. The listed inductance and temperature coefficient are technical specifications and should not be interpreted as a guarantee of accuracy or reliability under every operating condition.
A CSR current sensing resistor can be used in the current-sampling path of a power supply circuit. Engineers should select the resistance value based on circuit current, sensing voltage, power dissipation, and thermal conditions to support current monitoring or control feedback.
In power conversion and electronic power control circuits, a low resistance resistor can provide a current-sensing function. Selection should account for rated power, actual current, pulse conditions, and PCB heat dissipation to avoid exceeding the permitted load.
CSR resistors can be considered for circuit nodes where current variations need to be monitored in industrial control boards and electronic control equipment. Low inductance is a useful selection parameter for some higher-frequency circuit designs, although suitability must be verified against circuit frequency and layout.
In circuits incorporating overcurrent monitoring or current feedback, a current sensing resistor can serve as the sensing element. Engineers should determine resistance and power ratings based on monitored current, allowable voltage drop, measurement accuracy, and thermal dissipation requirements.
