Microphones Procurement Notes

Verify the specific suffix against official documentation, as variants like PNM-3546L-C3310-R exist with distinct electrical characteristics. Confirm RoHS compliance status through current manufacturer declarations. Ensure the selected variant matches the required operating voltage and sensitivity specifications for the target application circuit design.

Microphones Selection Notes

Select this component when a standard 6 mm omnidirectional microphone is required. Compare sensitivity levels against other series members to ensure adequate signal-to-noise ratio. Verify that the 2 VDC operating requirement aligns with the system power supply architecture before finalizing the part selection.

Microphones Part Context

This microphone belongs to the PNM series within PUI Audio's audio device portfolio. It shares dimensional similarities with other 6 mm microphones but differs in electrical parameters such as impedance and sensitivity. The series provides standardized mounting options for various audio sensing applications.

Microphones Replacement Considerations

POM-3546L-3-R offers similar dimensions with SMD termination. POM-2246L-C33-R provides a lower profile option. Verify electrical compatibility and mounting method differences before substituting.
