AOM-5242L-R

Overview

The AOM-5242L-R is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern and operates within a voltage range of 1.5 V to 10 V. The device has a sensitivity of -42 dB ±2 dB and an impedance of 2.2 kOhms. It utilizes solder pad termination for circuit integration. Physical dimensions include a diameter of 9.7 mm (0.382 inches) and a depth of 4.5 mm.

Feature Summary

• Omnidirectional acoustic response for uniform sound capture from all directions
• Analog output signal suitable for direct interfacing with audio processing circuits
• Electret condenser design providing consistent performance across operating voltages

Applications

• Consumer electronic devices requiring compact audio input
• Voice recognition systems utilizing analog microphone interfaces
• General-purpose audio recording equipment

Procurement Notes

Verify the specific datasheet version for the AOM-5242L-R to confirm exact electrical tolerances and mechanical drawings. Ensure compatibility with the target circuit's biasing requirements, as the component operates within a specified voltage range. Cross-reference the manufacturer's official documentation for any updates regarding RoHS compliance status or pinout configurations before finalizing procurement specifications.

Selection Notes

Select this component when an omnidirectional analog microphone is required for space-constrained designs. The 9.7 mm diameter allows for standard mounting holes in various enclosures. Consider the -42 dB sensitivity level against the noise floor of the subsequent amplifier stage. Verify that the solder pad termination method aligns with the printed circuit board assembly process used in the manufacturing line.

Part Context

This part belongs to the AOM series of microphones from PUI Audio, Inc., which includes various models with different sensitivities and form factors. The AOM-5242L-R specifically denotes the -42 dB sensitivity variant with a 9.7 mm diameter. It is distinct from higher sensitivity models like the AOM-5024L-HD-R (-24 dB) and differs in termination style from surface-mount variants.

Replacement Considerations

The AOM-5242L-R may be substituted with other PUI Audio AOM series microphones sharing the same 9.7 mm diameter and solder pad termination, provided the sensitivity difference is acceptable for the application. Models such as the AOM-5242L without the suffix should be verified for identical electrical characteristics.
