Microphones Procurement Notes

Verify the specific suffix variant required, as POM-1644P-NF-R denotes a reel-packaged version while POM-1644P-NF may indicate tape-and-reel or bulk depending on distributor classification. Confirm RoHS compliance status directly with the manufacturer datasheet. Ensure the ordering suffix matches the intended packaging format for automated assembly processes. Cross-reference the part number with official PUI Audio documentation to confirm current production status and availability.

Microphones Selection Notes

Select this component when an omnidirectional electret microphone with analog output is required for compact designs. The 6mm form factor suits space-constrained enclosures. Verify that the operating voltage aligns with the system's 1.3V to 10V supply range. Consider the -44dB sensitivity and 60dB SNR for applications requiring moderate audio fidelity. Ensure mechanical mounting via PC pins is compatible with the PCB layout.
