AOM-6742L-R

Overview

The AOM-6742L-R is an omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a cylindrical design with dimensions of 9.7 mm in diameter and length, and 4.5 mm in depth. The device operates at a voltage of 1.5 V and has an impedance of 2.2 kOhms. Its sensitivity is rated at -42 dB ±3dB, with a frequency response range spanning from 30 Hz to 15 kHz. The component utilizes solder pin termination for circuit integration.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture
• Electret condenser transducer technology for analog audio output
• Compact cylindrical form factor suitable for space-constrained designs

Applications

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

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's current datasheet to confirm dimensional tolerances and terminal configuration. Ensure the operating voltage aligns with the 1.5 V specification provided in official documentation before finalizing the power supply design.

Selection Notes

Select this component when an omnidirectional response is required within a compact cylindrical housing. The 2.2 kOhm impedance and -42 dB sensitivity are key parameters for matching pre-amplifier stages. Confirm that the solder pin termination method is compatible with the target PCB assembly process.

Part Context

This part belongs to the AOM series of microphones from PUI Audio, Inc., a company specializing in audio components including speakers, transducers, and indicators. The series offers various configurations tailored for appliances, industrial, and consumer applications.

Replacement Considerations

The AOM-6738P-R shares similar dimensions but differs in sensitivity (-38 dB) and uses SMD/SMT termination instead of solder pins. Verify electrical compatibility if substituting.
