CS0305U

Current Sensors Overview

The CS0305U is a unipolar open-loop current sensor module manufactured by Same Sky. It features a Hall effect sensing element designed for precise DC and low-frequency AC current measurement up to 40 kHz. The device operates within a supply voltage range of 4.75V to 5.25V, consuming a maximum supply current of 25mA. It provides a proportional voltage output relative to the sensed current, which is rated at 10A. The sensor exhibits an accuracy of ±4.2% and a linearity of ±0.5%, with a fast response time of 7µs. Designed for through-hole mounting, it functions reliably in temperatures ranging from -10°C to 75°C.

Current Sensors Procurement Notes

Verify the specific suffix or variant against the official Same Sky datasheet to ensure compatibility with required accuracy and package specifications. Confirm that the unipolar nature aligns with the application's current direction requirements. Check for RoHS3 compliance status if environmental regulations are mandatory. Ensure the through-hole mounting style fits the target PCB layout constraints before ordering.

Current Sensors Selection Notes

Select this component when a cost-effective solution for measuring moderate currents up to 10A is required without the complexity of closed-loop systems. Consider the ±4.2% accuracy sufficient for general monitoring rather than precision metering. Evaluate the 7µs response time against the switching frequency of the target circuit to ensure adequate signal fidelity. Verify that the 5V logic-compatible output voltage range matches the input requirements of the downstream microcontroller or ADC.
