AOM-4542L-R

Overview

The AOM-4542L-R is an omnidirectional analog condenser microphone manufactured by PUI Audio. It features a cylindrical form factor with a diameter of 9.7 mm and a depth of 4.70 mm. The device operates at a supply voltage of 2 V and presents an impedance of 2.2 kOhms. Its sensitivity is rated at -42 dB. The component utilizes solder pin termination for circuit integration.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Analog condenser transducer technology for signal conversion
• Low-voltage operation capability suitable for portable electronics

Applications

• Consumer electronic audio input devices
• Industrial control panel voice interfaces
• Medical equipment communication systems

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact mechanical dimensions and electrical tolerances. Confirm availability status as distribution channels may list obsolete or discontinued inventory. Ensure the solder pin configuration matches the target PCB footprint design requirements before finalizing procurement orders.

Selection Notes

Select this component when an omnidirectional response is required within a constrained cylindrical volume. The 2.2 kOhm impedance and -42 dB sensitivity define the interface requirements for the preamplifier stage. Verify that the 2 V operating voltage aligns with the system power budget and that the through-hole solder pin termination is compatible with the assembly process.

Part Context

This part belongs to the AOM series of microphones produced by PUI Audio, Inc., a manufacturer specializing in audio components such as speakers, transducers, and indicators. The company provides standard and custom audio solutions for various industrial and consumer applications based in Dayton, Ohio.

Replacement Considerations

The AOM-4542P-NF-R is a related variant within the same product family. Engineers should verify if the physical depth or specific termination style differences between the L and P suffixes impact the mechanical enclosure design.
