Overview
The AOM-4546P-NF-R is an omnidirectional electret microphone manufactured by PUI Audio. It features a cylindrical design with a diameter of 9.7 mm and a depth of 4.5 mm. The component operates at a supply voltage of 1.5 V and provides a sensitivity of -46 dB. Its nominal impedance is 2.2 kOhms, and it utilizes SMD/SMT termination for surface mount integration.
Feature Summary
- Omnidirectional acoustic response for uniform sound capture from all directions
- Surface mount solder pin configuration for automated PCB assembly
- Low voltage operation suitable for portable battery-powered devices
Applications
- Consumer audio recording equipment
- Portable communication devices
- Voice recognition modules
Procurement Notes
Verify the specific suffix NF-R against official datasheets to confirm the absence of noise filters or specific housing variations. Confirm RoHS compliance status through current manufacturer documentation as regulatory requirements may change over time. Ensure compatibility with existing surface mount footprints during procurement planning.
Selection Notes
Select this component when a low-profile, surface-mount omnidirectional microphone is required for compact designs. The 1.5 V operating voltage makes it suitable for single-cell battery applications. Compare sensitivity and impedance specifications against circuit interface requirements to ensure proper signal conditioning without excessive amplification.
Part Context
This part belongs to the AOM series of microphones from PUI Audio, which focuses on standard form factor audio sensors. The series includes various diameters and termination types to accommodate different enclosure constraints and manufacturing processes within the consumer electronics sector.
Replacement Considerations
Direct substitutes are not explicitly confirmed in available public data. Evaluate alternatives based on matching 9.7 mm diameter, 2.2 kOhm impedance, and -46 dB sensitivity. Verify that any replacement supports 1.5 V operation and SMD mounting.
