AOM-4544P-NF

Overview

The PUI Audio AOM-4544P-NF is an omnidirectional analog condenser microphone designed for audio signal capture. It features a cylindrical housing with a diameter and length of 9.7 mm and a depth of 4.5 mm. The component operates at a supply voltage of 1.5 V, providing a sensitivity of -44 dB and an impedance of 2.2 kOhms. Electrical connections are established via solder pins, facilitating integration into printed circuit boards.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound reception from all directions
• Analog output suitable for direct interfacing with standard audio processing circuits
• Compact cylindrical form factor enabling installation in space-constrained electronic assemblies

Applications

• Consumer electronics audio input modules
• Voice recognition system microphones
• General purpose sound detection devices

Procurement Notes

Verify the complete part number including suffixes such as NF or R against official manufacturer documentation to ensure correct impedance and termination specifications. Confirm RoHS compliance status through current datasheets prior to procurement. Cross-reference Mouser part numbers for accurate identification during sourcing processes.

Selection Notes

Select this component when an omnidirectional response is required for ambient sound capture. Ensure the design supports a 1.5 V operating voltage and accommodates the specified 2.2 kOhm impedance load. Verify that the physical dimensions fit within the available enclosure space and that solder pin termination matches the board layout.

Part Context

This microphone belongs to the AOM series of analog omnidirectional microphones manufactured by PUI Audio. The series offers various sensitivity and impedance configurations to suit different audio application requirements while maintaining consistent physical mounting standards across the product line.

Replacement Considerations

The AOM-4544P-3-R serves as a functional alternative within the same series, offering identical sensitivity but differing in impedance specification. Evaluate circuit compatibility regarding impedance matching before substituting components.
