AOM-5244L-R

Overview

The AOM-5244L-R is an omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a compact cylindrical design with a diameter of 9.7 mm and a height of 4.5 mm. The component utilizes SMD/SMT solder pad termination for surface mount assembly. Key electrical specifications include an impedance of 1000 ohms (1 kOhm) and a sensitivity of -44 dB ±3 dB. It operates within a supply voltage range of 1.5 V to 10 V DC, with a typical operating voltage of 4.5 V. The frequency response spans from 30 Hz to 15 kHz or 100 Hz to 20 kHz depending on the specific datasheet reference.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser transducer technology for reliable audio signal conversion
• Surface mount solder pad termination for automated PCB assembly integration

Applications

• Consumer electronics audio input devices
• Industrial control panel voice interfaces
• Medical equipment monitoring systems
• Security and fire alarm notification units

Procurement Notes

Verify the specific revision of the datasheet regarding the frequency response range, as sources cite both 30 Hz–15 kHz and 100 Hz–20 kHz. Confirm the exact operating voltage requirements for your circuit design, as the part supports a wide range from 1.5 V to 10 V. Ensure that the soldering process parameters are compatible with the SMD pad configuration to maintain mechanical stability and electrical integrity during assembly.

Selection Notes

Select this component when an omnidirectional pickup pattern is required for general ambient sound capture rather than directional focusing. The wide operating voltage range allows flexibility in power supply design across various battery-operated and mains-powered devices. Consider the physical dimensions of 9.7 mm diameter when evaluating space constraints on the printed circuit board layout compared to other microphone form factors.

Part Context

This microphone belongs to the AOM series of audio components produced by PUI Audio, Inc., a manufacturer specializing in audio solutions for industrial, medical, and consumer markets. The company has over 40 years of experience in designing transducers and indicators. This specific model represents their standard line of compact electret microphones designed for cost-effective mass production applications requiring reliable audio input capabilities.

Replacement Considerations

Direct substitutes may include other omnidirectional electret microphones with similar 9.7 mm diameters and 1 kOhm impedance, such as the AOM-6746L-R or AUM-5247L-R, provided the sensitivity and voltage requirements align with the original design specifications.
