POM-5242L-R

Microphones Overview

The POM-5242L-R is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern and operates within a supply voltage range of 2 V to 10 V. The component exhibits a sensitivity of -42 dB ±3 dB and a signal-to-noise ratio of 60 dB. Its impedance is specified as 2.2 kOhms. The physical dimensions are approximately 5.40 mm in width, with SMD/SMT solder pad termination for surface mount integration.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture from all directions
• Analog electret condenser transducer technology
• Surface mount device (SMD) configuration for automated assembly

Microphones Applications

• Consumer electronics audio input
• Industrial control panel voice communication
• Medical equipment user interface

Microphones Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm reel packaging specifications and tape-and-reel compatibility. Ensure the operating voltage requirements of your circuit align with the 2 V to 10 V range. Confirm availability status directly with authorized distributors as lifecycle status may vary.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general ambient sound pickup rather than directional focusing. The 2.2 kOhm impedance must be compatible with the input stage of the connected amplifier or ADC. Verify that the PCB footprint matches the 5.40 mm width dimension for proper mechanical fit.

Microphones Part Context

This part belongs to PUI Audio's line of standard analog microphones designed for compact electronic assemblies. It serves as a cost-effective solution for basic voice detection and audio sensing applications where high-fidelity recording is not the primary requirement.

Microphones Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement. Evaluate alternative omnidirectional electret microphones with similar 2.2 kOhm impedance and 2-10 V operating ranges if sourcing is restricted.
