POM-2742L-2

Microphones Overview

The POM-2742L-2-R is an analog omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a circular shape with a maximum height of 0.126 inches (3.20mm) and a diameter of 0.236 inches (6mm). The device operates within a voltage range of 2V to 10V and exhibits a sensitivity of -42dB +/-3dB (7.94 mV/Pa). It provides a signal-to-noise ratio of 60 dB and supports a frequency response from 30Hz to 15kHz. Electrical connections are made via solder pads.

Microphones Procurement Notes

Verify the specific suffix 'R' in the part number POM-2742L-2-R against official PUI Audio documentation to confirm reel packaging or specific variant attributes. Ensure the required operating voltage aligns with the 2V to 10V specification. Confirm that the -42dB sensitivity meets the system's noise floor requirements. Check datasheet revisions for any dimensional changes.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general-purpose voice capture. The wide operating voltage range allows flexibility in power supply design. The low profile facilitates integration into space-constrained devices. Verify that the solder pad termination method matches the PCB assembly process.

Microphones Part Context

POM-2742L-2-R belongs to PUI Audio's line of standard electret condenser microphones. These components are designed for reliable performance in various electronic assemblies. The series offers standardized dimensions and electrical characteristics to simplify engineering integration across multiple product categories.

Microphones Replacement Considerations

Direct substitutes require matching the -42dB sensitivity, 6mm diameter, and omnidirectional pattern. Verify pinout compatibility if alternative manufacturers offer similar form factors. Consult PUI Audio for approved cross-references.
