Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to ensure correct impedance and sensitivity ratings. Confirm RoHS compliance status through current datasheets prior to procurement. Cross-reference part numbers with authorized distributors to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when an omnidirectional response is required within a compact cylindrical form factor. Ensure the circuit design supports the 1.5 V operating voltage and matches the 2.2 kOhm impedance requirements. Verify that the physical dimensions fit the available space constraints in the target enclosure.

Part Context

This microphone belongs to the AOM series from PUI Audio, which focuses on standard omnidirectional electret condenser microphones. The series offers various impedance and sensitivity options to suit different audio input requirements across consumer electronics applications.

Replacement Considerations

The AOM-4544P-3-R serves as a verified alternative within the same series, offering identical physical dimensions but differing in impedance specifications.
