Current Sensors Procurement Notes

Verify that the application circuit provides the required ±12V to 15V dual supply rails, as this component cannot operate on single-ended power. Confirm that the load current does not exceed the 36A rating to prevent saturation or damage. Ensure the PCB layout accommodates the specific through-hole module footprint and allows sufficient clearance for the magnetic core aperture. Check for any recent product change notices regarding pinout or packaging updates before finalizing the design.

Current Sensors Selection Notes

Select this model when precise bidirectional current monitoring is required in environments demanding high bandwidth up to 150kHz. The closed-loop architecture offers superior linearity compared to open-loop alternatives, making it suitable for sensitive control loops. Consider the physical size of the single-pass module and the need for external shunt resistors if interfacing with standard analog-to-digital converters. Evaluate thermal dissipation requirements based on the supply current and ambient operating conditions.
