AOM-6738L-R

Overview

The AOM-6738L-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a 9.7 mm overall diameter and a height of 6.7 mm with solder pads for surface mount installation. The device operates at a supply voltage of 1.5 V and has an impedance of 2.2 kOhms. Key electrical specifications include a sensitivity of -38 dB ±3 dB, a frequency range of 20 Hz to 16 kHz, a signal-to-noise ratio of 60 dB, and an acoustic overload point of 110 dB.

Feature Summary

• Omnidirectional polar pattern for uniform sound capture from all directions
• Electret condenser transducer technology ensuring distortion-free response
• Surface mount design with solder pads for automated PCB assembly

Applications

• Consumer audio recording devices
• Voice recognition systems
• Portable electronic equipment

Procurement Notes

Verify the specific suffix 'L' in the part number AOM-6738L-R against official datasheets to confirm lead wire mounting configuration versus standard SMD variants. Ensure compatibility with 1.5 V operating voltage requirements in the target circuit design before procurement.

Selection Notes

Select this component when an omnidirectional response is required within a compact 9.7 mm form factor. The 2.2 kOhm impedance and -38 dB sensitivity are suitable for general-purpose voice pickup applications requiring low power consumption at 1.5 V operation.

Part Context

This model belongs to the AOM series of microphones from PUI Audio. The series includes various configurations differing in directivity, impedance, and mounting style. The AOM-6738L-R specifically denotes the 2.2 kOhm impedance variant with lead wire or specific mounting characteristics distinct from other series members like the AOM-6746L-R.

Replacement Considerations

The AOM-6738P-R is a related variant within the same series but differs in impedance (2.2 kOhm vs unspecified difference) and potentially mounting style. Verify exact pinout and mechanical dimensions before substitution.
