Microphones Procurement Notes

Verify the specific ordering suffix against the manufacturer's official part numbering system to ensure correct termination and packaging options. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure design-in compatibility with existing PCB footprints and biasing circuits.

Microphones Selection Notes

Select this component when an omnidirectional response is required within a 50 Hz to 16 kHz bandwidth. The 2.2 kohm impedance and -42 dB sensitivity are suitable for standard analog audio interfaces. Verify that the operating voltage range of 2 VDC to 10 VDC aligns with the target system power supply constraints.

Microphones Part Context

This model belongs to the PUI Audio microphone portfolio, specifically designed as a cost-effective solution for mass-produced electronic devices. It represents a standard form factor commonly used in consumer audio applications where size constraints and broad frequency capture are prioritized over high-fidelity studio-grade performance.

Microphones Replacement Considerations

Cross-reference with other PUI Audio ECM models sharing identical dimensions and electrical parameters. Verify pinout compatibility and mounting hole positions before substituting with alternative manufacturers' components to ensure mechanical fit.
