SOM-1844P

Overview

The SOM-1844P is an electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional pickup pattern and provides analog audio output. The device operates within a supply voltage range of 2 V to 10 V with a typical supply current of 500 µA. Key electrical specifications include a sensitivity of -44 dB ±3 dB, a signal-to-noise ratio of 58 dB, and an impedance of 2.2 kOhms. The component utilizes PC pins for board mounting and is housed in a compact 6 mm diameter package.

Feature Summary

Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
Electret condenser technology providing analog audio signal output
Low power consumption design suitable for battery-operated applications

Applications

Analog audio capture systems
Consumer electronics devices
Industrial control panels requiring voice input

Procurement Notes

Verify the specific datasheet version for the SOM-1844P to confirm exact mechanical dimensions and pinout configurations before finalizing PCB layout. Ensure that the target application circuit provides the required 2 V to 10 V DC bias voltage and matches the 2.2 kOhm impedance requirements for optimal performance. Confirm RoHS compliance status through official manufacturer documentation.

Selection Notes

Select this component when an omnidirectional response is required for general-purpose audio sensing. The fixed -44 dB sensitivity and 58 dB SNR define the acoustic performance envelope. Consider the 6 mm form factor and PC pin termination method for compatibility with existing assembly processes and enclosure constraints.
