AOM-4544L

Overview

The AOM-4544L is an omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a circular shape with dimensions of 0.382 inches in length and 0.1181 inches in thickness. The device operates within a supply voltage range of 1.5 V to 10 V and has an impedance of 2.2 kOhms. Key electrical specifications include a sensitivity of -44 dB ±3 dB (equivalent to 15.85 mV/Pa) and a signal-to-noise ratio of 67 dB. The frequency response spans from 30 Hz to 15 kHz.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture
• Electret condenser transducer technology
• Low operating voltage compatibility

Applications

• General purpose audio recording
• Voice recognition systems
• Consumer electronic devices

Procurement Notes

Verify the specific suffix requirements when ordering, as variants such as AOM-4544L-R may differ in packaging or termination style. Confirm that the selected component matches the required impedance and sensitivity tolerances for the target circuit design. Ensure compatibility with the intended operating voltage range before finalizing procurement decisions.

Selection Notes

Select this component based on its omnidirectional characteristic and standard electret condenser performance metrics. Consider the physical dimensions of 0.382 x 0.1181 inches for space-constrained designs. Evaluate the 67 dB SNR and -44 dB sensitivity against the noise floor and gain requirements of the application circuit.

Part Context

This model belongs to the PUI Audio line of analog microphones. It is part of a series offering various form factors and electrical characteristics for integration into portable and stationary audio equipment. The product utilizes standard solder pad connections for PCB mounting.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Equivalent components must match the 2.2 kOhm impedance, -44 dB sensitivity, and 1.5-10 V operating range while maintaining similar physical dimensions.
