POM-2738L-R

Microphones Overview

The POM-2738L-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a 6 mm overall diameter and a height of 2.7 mm with solder pads for surface mount termination. The device operates at a supply voltage of 2 VDC with a current rating of 500 µA. Key electrical specifications include an impedance of 2.2 kOhms, a sensitivity of -38 dB ±3dB, and a signal-to-noise ratio of 60 dB. The frequency response range spans from 50 Hz to 16 kHz.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Compact form factor suitable for space-constrained assemblies
• Analog output type for direct interface with audio circuits

Microphones Applications

• Consumer electronics audio input
• Industrial control panel voice commands
• Medical device speech recognition interfaces

Microphones Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the solder pad footprint matches your PCB layout requirements. Ensure the operating voltage and current draw align with your system's power budget. Check RoHS compliance status if required by your regional regulations.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog audio applications. The 6 mm diameter and 2.7 mm height make it suitable for compact enclosures. The 2.2 kOhm impedance and 2 VDC operation are standard for many consumer audio preamplifiers. Consider the -38 dB sensitivity for typical voice pickup distances in close-proximity devices.

Microphones Part Context

This part belongs to PUI Audio's line of electret condenser microphones designed for general-purpose audio sensing. The company specializes in audio components for medical, industrial, and consumer markets. The POM series typically offers various mounting options and acoustic characteristics to suit different enclosure designs and sound pressure level requirements.

Microphones Replacement Considerations

The POM-2740P-C33-R shares similar dimensions and electrical characteristics but uses solder pins instead of pads. Verify mechanical compatibility and pinout alignment before substitution. Other models in the POM series may differ in sensitivity or height.
