AOM-6738P-R

Overview

The AOM-6738P-R is an omnidirectional electret microphone manufactured by PUI Audio. It features a cylindrical design with a diameter of 9.7 mm and a length of 9.7 mm. The component operates at a supply voltage of 1.5 V and has an impedance of 2.2 kOhms. Its sensitivity is rated at -38 dB. The device utilizes surface-mount (SMD/SMT) termination for PCB integration.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Surface-mount soldering compatibility
• Low-voltage operational capability

Applications

• Consumer electronic audio input devices
• Portable communication equipment
• Voice recognition modules

Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm packaging and reel specifications. Ensure the SMD footprint matches the ECAD model provided by PUI Audio before finalizing the board layout. Confirm RoHS compliance status through official documentation.

Selection Notes

Select this component when a low-profile, surface-mount omnidirectional microphone is required. The 2.2 kOhm impedance and -38 dB sensitivity suit general voice capture applications. Verify that the 1.5 V operating voltage aligns with the target circuit's power supply rails.

Part Context

This part belongs to the AOM series of microphones from PUI Audio. The series includes various configurations differing in termination type, dimensions, and electrical characteristics. This specific model represents the surface-mount variant within the lineup.

Replacement Considerations

Cross-reference with other AOM series parts such as AOM-6545P-R or AOM-4544P-NF-R if pin-out or form factor adjustments are permissible. Verify impedance and sensitivity differences to ensure signal chain compatibility.
