• High-definition design optimized for extreme fidelity and focused recording
• Wide operating voltage range supporting flexible circuit integration

Microphones Applications

• Acoustic source recording
• On-axis and off-axis audio capture
• General-purpose analog microphone circuits

Microphones Procurement Notes

Verify the specific datasheet version for the POM-2739L-HD3-LW100-R to confirm mechanical dimensions and electrical tolerances. Ensure the application circuit provides the required 1 VDC to 10 VDC supply range. Confirm that wire lead termination matches the target PCB or harness assembly requirements before finalizing procurement.

Microphones Selection Notes

Select this component when high-fidelity audio reproduction is required in a compact 6mm form factor. The wide voltage tolerance allows compatibility with various low-power systems. Consider the wire lead style if through-hole or direct wiring is preferred over surface-mount alternatives.

Microphones Part Context

This model belongs to PUI Audio's HD series of microphones, which are engineered for enhanced audio performance compared to standard variants. The part utilizes an electret condenser element housed in a 6mm cylindrical package, distinguishing it from larger or differently terminated models in the broader product catalog.

Microphones Replacement Considerations

Direct substitutes include other 6mm omnidirectional electret microphones with similar -39 dB sensitivity and 2.2 kOhm impedance. Verify pinout and voltage compatibility when considering alternative brands.
