Microphones Procurement Notes

Verify the specific sensitivity tolerance and impedance values against the latest manufacturer datasheet, as variations may exist between production batches. Confirm that the solder pin configuration matches the target PCB footprint requirements. Ensure the operating voltage aligns with the 2 VDC to 10 VDC specification during system power budgeting. Cross-reference RoHS compliance documentation if required for regulatory adherence.

Microphones Selection Notes

Select this component when an omnidirectional pickup pattern is required within a strict cylindrical volume constraint. The 2.2 kOhm impedance is compatible with standard preamplifier inputs. Consider the 68 dB SNR for applications requiring moderate noise performance. Verify that the solder pin termination method fits the assembly process capabilities compared to SMD alternatives.

Microphones Part Context

This part belongs to the POM series of electret condenser microphones from PUI Audio. The series is characterized by small form factors and analog output interfaces. It serves as a fundamental acoustic sensor component in various audio signal chain architectures.

Microphones Replacement Considerations

Direct substitutes must match the 6x6x3.5 mm cylindrical package, 2.2 kOhm impedance, and solder pin termination. Verify equivalent sensitivity and SNR ratings to maintain system audio performance levels.
