Procurement Notes

Verify component authenticity through authorized distributors to ensure compliance with original manufacturing standards. Confirm that the specific revision matches project requirements, as the product status is listed as discontinued. Request updated documentation to validate electrical tolerances and physical dimensions before finalizing procurement plans.

Selection Notes

Evaluate the low impedance and high current consumption against available power rails. Ensure the operating voltage aligns with the system's 1.3 V requirement. Consider the limited frequency response when selecting for applications demanding extended high-frequency audio fidelity. Verify mechanical clearance against the specified maximum height and footprint dimensions.
