Procurement Notes

Verify the specific suffix designation when sourcing, as variations may exist between tape-and-reel and tube packaging formats. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the procurement channel provides traceability for this discontinued or limited-stock component type.

Selection Notes

Select this component for applications requiring precise single-phase energy measurement with minimal external calibration requirements. Consider the 24-SSOP package constraints for PCB layout and thermal management. Evaluate compatibility with existing microcontroller interfaces, as the device relies on serial communication protocols for data output and configuration.
