POW-1644P-B-R

Microphones Overview

The POW-1644P-B-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It operates within a frequency range of 50 Hz to 16 kHz and features a sensitivity of -44 dB ±3 dB. The device requires a supply voltage between 2 VDC and 10 VDC, with a typical current consumption of 500 µA. It presents an impedance of 2.2 kohm and includes PC pins for termination. The unit supports a maximum supply voltage of 10 VDC.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser transducer technology for analog audio signal output
• Wide frequency response covering low-frequency bass to high-frequency treble

Microphones Applications

• Consumer electronics audio input devices
• Industrial control panel voice communication
• Medical equipment user interface microphones

Microphones Procurement Notes

Verify the specific suffix requirements against the manufacturer's latest datasheet to ensure correct pin configuration and mounting style compatibility. Confirm that the operating voltage range aligns with your system's power supply rails. Check RoHS compliance documentation if required for your region. Ensure mechanical clearance accommodates the PC pin length and housing dimensions during PCB layout.

Microphones Selection Notes

Select this component when an omnidirectional response is necessary for ambient noise capture or voice recognition in open environments. The wide frequency range suits applications requiring broad audio fidelity rather than narrowband speech enhancement. Consider the low current draw for battery-powered designs. Verify that the PC pin termination method fits the available PCB mounting constraints compared to surface mount alternatives.
