AOM-6746L-R

Overview

The AOM-6746L-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a cylindrical design with a diameter and length of 9.7 mm and a depth of 5.2 mm. The component operates at a supply voltage of 4.5 V and utilizes SMD/SMT termination for surface mount integration. Key electrical specifications include an impedance of 1 kOhm and a sensitivity of -46 dB.

Feature Summary

• Omnidirectional acoustic response for uniform sound capture from all directions
• Surface mount device (SMD/SMT) configuration for automated PCB assembly
• Electret condenser transducer technology for audio signal conversion

Applications

• Consumer electronic audio input devices
• Portable communication equipment
• General purpose voice recording modules

Procurement Notes

Verify the specific manufacturer part number against official distributor catalogs to ensure accuracy. Confirm RoHS compliance status through current documentation. Check for any recent engineering changes or lifecycle notifications that may affect long-term availability or specification consistency before finalizing procurement plans.

Selection Notes

Select this component when a low-profile, surface-mountable microphone is required for compact designs. The 4.5 V operating voltage and 1 kOhm impedance must align with the target circuit's biasing requirements. Ensure the PCB footprint matches the 9.7 mm diameter and 5.2 mm depth constraints.

Part Context

This microphone belongs to the AOM series from PUI Audio, which focuses on standard-sized omnidirectional microphones. The series offers various termination types and voltage ratings to accommodate different manufacturing processes and power budgets within consumer audio applications.

Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference impedance, sensitivity, and physical dimensions to ensure mechanical and electrical compatibility without redesigning the host circuit.
