Microphones Procurement Notes

Verify the specific suffix designation, such as -R, when ordering, as it may indicate reel packaging variations rather than functional differences. Confirm RoHS compliance status and lead-free availability through official manufacturer documentation prior to procurement. Ensure the selected variant matches the required mechanical dimensions and solder pad configuration for your PCB layout.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general audio capture applications. Consider the -46 dB sensitivity specification against your circuit's gain requirements. Verify that the operating voltage range of 2 V to 10 V aligns with your system power supply. Check mechanical constraints, specifically the 6 mm diameter and 2.90 mm height, to ensure compatibility with your enclosure design.

Microphones Part Context

This part belongs to the POM series of electret condenser microphones from PUI Audio, Inc.
