POM-2730L-HD-R

Microphones Overview

The POM-2730L-HD-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a sensitivity of -45 dB and operates at a working voltage of 2 V with a current rating of 500 uA. The device has an impedance of 2.2 kOhms and utilizes SMD/SMT termination for surface mount integration. Its physical dimensions are 6 mm in diameter, 4 mm in length, 4 mm in width, and 1.5 mm in depth.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern
• Surface mount (SMD/SMT) termination style
• Electret condenser transducer technology

Microphones Applications

• Consumer electronic audio input devices
• Portable communication equipment
• Embedded voice recognition systems

Microphones Procurement Notes

Verify the specific suffix 'HD' against the manufacturer's official documentation to confirm any distinct performance or material variations compared to standard variants. Ensure that the SMD footprint matches the design requirements, as the component requires surface mount assembly techniques compatible with the specified 6 mm diameter package.

Microphones Selection Notes

Select this component when a low-profile surface mount solution is required for compact audio designs. The 2 V operating voltage and 2.2 kOhm impedance are suitable for standard biasing circuits. Consider the 1.5 mm depth constraint for strict height limitations within the target enclosure.

Microphones Part Context

This part belongs to the HD series of microphones from PUI Audio, designed for high-density mounting applications. It serves as a specialized variant within the broader POM product line, distinguished by its specific dimensional profile and surface mount configuration for automated assembly processes.

Microphones Replacement Considerations

The POM-2742P-2-R is a comparable surface mount option but differs in physical depth (2.2 mm vs 1.5 mm). Verify mechanical clearance before substitution.
