AOM-4546L

Overview

The AOM-4546L is an omnidirectional electret condenser microphone manufactured by PUI Audio. It operates within a voltage range of 1.5 V to 10 V and features a sensitivity of -46 dB ±3 dB. The device supports an analog output with a frequency response spanning from 20 Hz to 19 kHz. Its physical dimensions are characterized by a diameter and length of 9.7 mm, with a depth of 4.75 mm. The component utilizes solder pads for surface mount termination.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture
• Electret condenser transducer technology for analog signal generation
• Surface mount termination configuration for automated assembly

Applications

• Consumer electronics audio input
• Industrial control panel voice communication
• Medical equipment monitoring systems

Procurement Notes

Verify the specific suffix (e.g., -R) against the required datasheet revision and packaging format. Confirm that the operating voltage aligns with the 1.5 V to 10 V specification. Ensure the solder pad termination matches the PCB layout requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement.

Selection Notes

Select this component when an omnidirectional response is required for general-purpose audio capture. The wide supply voltage range allows flexibility in circuit design. Verify that the 9.7 mm form factor fits the available enclosure space. Consider the -46 dB sensitivity level relative to the target signal-to-noise ratio requirements of the application.

Part Context

This part belongs to the AOM series of microphones from PUI Audio, which focuses on compact audio solutions. The series includes various configurations tailored for different mounting and electrical needs. The AOM-4546L specifically addresses applications requiring standard omnidirectional characteristics in a small footprint.

Replacement Considerations

The AOM-4546L-R is a verified variant with identical electrical specifications but potentially different packaging or reel options. Check for lead-free or specific environmental compliance updates in newer revisions.
