POW-2744P-B-R

Microphones Overview

The POW-2744P-B-R is an omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It operates within a frequency range of 50 Hz to 16 kHz and requires a supply voltage between 2 VDC and 10 VDC. The device features a sensitivity of -44 dB ±3dB and a maximum current consumption of 500 µA at 2 VDC. Its impedance is specified as 2.2 kohm. The component utilizes PC pins for mounting and has a circular shape with a diameter of 6.00 mm (0.236 inches) and a depth of 2.7 mm.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser technology providing analog audio output signals
• Low power consumption design suitable for battery-operated applications
• Through-hole PC pin termination for standard printed circuit board integration

Microphones Applications

• Consumer electronics requiring compact audio input solutions
• Industrial control panels and equipment monitoring systems
• Medical devices needing reliable voice or environmental audio capture

Microphones Procurement Notes

Verify the specific suffix requirements against the official PUI Audio datasheet to ensure correct terminal configuration and compliance standards. Confirm that the operating voltage range aligns with your system's power supply constraints. Check for RoHS compliance documentation if required by your manufacturing regulations. Ensure mechanical dimensions fit within the designated enclosure space before finalizing procurement.

Microphones Selection Notes

Select this component when an omnidirectional response is necessary for general ambient sound capture rather than directional focusing. Consider the -44 dB sensitivity level appropriate for moderate distance audio pickup scenarios. Evaluate the 2 VDC minimum supply requirement against available system voltages. The through-hole PC pin format dictates the PCB layout strategy compared to surface mount alternatives.

Microphones Part Context

This microphone belongs to the POW series produced by PUI Audio, Inc., a manufacturer specializing in audio components including transducers, speakers, and microphones. The company focuses on providing total sound solutions for various industries such as medical, industrial, and consumer electronics. This specific model represents their standard electret condenser offerings designed for reliable performance in diverse electronic assemblies.

Microphones Replacement Considerations

Cross-reference compatible parts using identical electrical parameters: -44 dB sensitivity, 2-10 VDC supply, and omnidirectional pattern. Verify mechanical compatibility regarding the 6.00 mm diameter and 2.7 mm depth. Ensure the replacement maintains the same PC pin configuration for direct board substitution without redesigning the footprint.
