Microphones Procurement Notes

Verify the specific suffix designation when ordering, as the base model POM-3542P may correspond to bulk packaging while variants like POM-3542P-R indicate reel packaging. Confirm terminal type and sensitivity tolerances against the official datasheet to ensure compatibility with the target circuit impedance and power supply requirements.

Microphones Selection Notes

Select this component for applications requiring a standard-sized, cost-effective omnidirectional microphone. Ensure the host circuit provides a bias voltage between 2 V and 10 V. The 6 mm form factor suits compact enclosures where space is limited but acoustic performance remains critical for clear voice transmission.

Microphones Part Context

This part belongs to the POM series of electret microphones from PUI Audio, Inc., a manufacturer specializing in audio components for industrial, medical, and consumer markets. The series offers various sizes and sensitivities, with the POM-3542P representing a standard 6 mm diameter option designed for general-purpose analog audio capture.

Microphones Replacement Considerations

Direct substitutes include the POM-3542P-R, which shares identical electrical characteristics but differs in packaging format. Other compatible options within the POM series should be evaluated based on matching sensitivity, impedance, and physical dimensions.
