Procurement Notes

Verify the specific suffix and tape-and-reel packaging details directly with the manufacturer or authorized distributors before ordering. Ensure that the requested part number matches the exact pinout and sensitivity specifications required for your design. Confirm compliance documentation such as RoHS status is available for the specific batch. Cross-reference the datasheet revision date to ensure compatibility with your system requirements.

Selection Notes

Select this component when a small form factor is critical for the application. Consider the sensitivity and supply voltage requirements against your system's power budget. Evaluate the thermal performance and mounting orientation constraints on the PCB. Compare alternative sensors if higher isolation voltage or digital interface is needed, as this model provides analog output.
