AOM-4544P-R

Overview

The PUI Audio AOM-4544P-R is an omnidirectional electret condenser microphone designed for audio signal capture. It features a cylindrical form factor with dimensions of 9.7 mm in diameter and length, and 4.5 mm in depth. The component operates at a supply voltage of 1.5 V and utilizes solder pin termination for circuit integration. Key electrical specifications include a nominal impedance of 2.2 kOhms and a sensitivity rating of -44 dB.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound reception from all directions
• Electret condenser transducer technology for reliable audio conversion
• Solder pin termination method facilitating direct board mounting

Applications

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

Procurement Notes

Verify the specific suffix designation during procurement to ensure correct impedance and sensitivity variants are obtained. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the Mouser part number 665-AOM4544PR for accurate sourcing channels and current availability status.

Selection Notes

Select this component when an omnidirectional response is required within a compact cylindrical housing. Ensure the design supports the specified 1.5 V operating voltage and accommodates the 2.2 kOhm impedance load. Verify that the physical footprint allows for the 9.7 mm diameter and 4.5 mm depth constraints.

Part Context

This microphone belongs to the AOM series manufactured by PUI Audio. The series comprises various electret condenser microphones differentiated primarily by sensitivity levels and impedance values. The AOM-4544P-R represents a standard configuration within this family, sharing common mechanical dimensions with other models in the lineup.

Replacement Considerations

The AOM-4544P-NF-R serves as a verified substitute within the same product line. Both components share identical mechanical dimensions, impedance, and sensitivity ratings. Selection between these variants should be based on specific manufacturing or packaging requirements documented in official datasheets.
