POM-2742P

Microphones Overview

The PUI Audio POM-2742P is an omnidirectional electret condenser microphone designed for audio signal capture. It operates at a supply voltage of 2 V and features a nominal impedance of 2.2 kOhms with a sensitivity of -44 dB. The device utilizes solder pin termination for circuit integration. Its physical dimensions are 6 mm in diameter and length, with a depth of 2.2 mm. This component is part of the POM series, engineered for reliable acoustic performance in compact electronic assemblies.

Microphones Feature Summary

• Omnidirectional polar pattern for uniform sound pickup from all directions
• Electret condenser technology for consistent audio transduction
• Solder pin termination for direct board mounting

Microphones Applications

• Consumer electronics audio input devices
• Voice recognition module integration
• Portable communication equipment

Microphones Procurement Notes

Verify the specific suffix (e.g., -R, -C33) against the required packaging format such as bulk or reel. Confirm that the 2.2 kOhm impedance and -44 dB sensitivity align with the target circuit design requirements before finalizing orders.

Microphones Selection Notes

Select this model when a low-profile, omnidirectional microphone is required for general voice capture applications. Ensure the PCB layout accommodates the 6 mm diameter footprint and that the biasing circuit supports the specified 2 V operating voltage and 2.2 kOhm load impedance.

Microphones Part Context

This component belongs to the POM series of microphones manufactured by PUI Audio. The series includes various configurations differing in height, termination style, and packaging. The POM-2742P represents a standard height variant within this lineup, distinguished by its specific dimensional profile and electrical characteristics suitable for general-purpose audio sensing.

Microphones Replacement Considerations

Cross-reference with other POM series variants like POM-2742P-C33-R or POM-2246P-2-R if different packaging or slight dimensional adjustments are needed. Verify that substitute parts maintain the same 2.2 kOhm impedance and 2 V operation to ensure circuit compatibility.
