Microphones Procurement Notes

Verify the specific suffix 'R' against the manufacturer's latest datasheet to confirm packaging or compliance variations. Ensure the operating voltage remains within the 2 VDC to 10 VDC range during circuit design. Confirm that the 2.2 kOhm impedance matches the pre-amplifier input requirements. Check RoHS and REACH status directly from the official documentation before finalizing procurement.

Microphones Selection Notes

Select this component when a unidirectional response is required to reduce ambient noise interference. The wide supply voltage range allows flexibility in power supply design. The low current consumption of 500 µA makes it suitable for battery-operated devices. Ensure the mechanical dimensions fit the available space on the printed circuit board.

Microphones Part Context

This part belongs to the PUI Audio family of analog microphones. It is distinct from omnidirectional models like the POM series and piezoelectric transducers. The product line focuses on providing reliable audio sensing solutions for various industrial and consumer applications.

Microphones Replacement Considerations

Direct substitutes may include other unidirectional electret microphones with similar electrical parameters. Verify pinout compatibility and mechanical footprint before substitution. Consult the manufacturer for approved alternate part numbers.
