POM-2735P

Microphones Overview

The POM-2735P is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern and PC pin termination for through-hole mounting. The device operates within a voltage range of 3 V to 10 V with a rated supply voltage of 3 V and a maximum current consumption of 500 µA. Key electrical specifications include a sensitivity of -35 dB ±2 dB and an impedance of 2.2 kOhms. The physical dimensions are 0.236 inches (6.00 mm) in diameter and 0.114 inches (2.90 mm) in maximum height.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture from all directions
• Electret condenser transducer technology providing analog audio output
• PC pin termination configuration suitable for standard printed circuit board assembly

Microphones Applications

• General purpose voice recording applications
• Consumer electronic audio input devices
• Industrial control panel voice interfaces

Microphones Procurement Notes

Verify the specific suffix designation against official documentation, as variants such as POM-2735P-R exist with identical core specifications but different packaging or reel configurations. Confirm that the required termination type matches the PC pin specification rather than surface mount alternatives. Ensure the operating voltage requirements align with the 3 V to 10 V range specified for this component family.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general voice pickup rather than directional isolation. The PC pin termination necessitates through-hole mounting processes, which may influence PCB layout and assembly method selection compared to surface mount options. Consider the 500 µA current draw and 2.2 kOhm impedance when designing the biasing and amplification circuitry to ensure signal integrity.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio, Inc., which focuses on compact electret condenser designs. The series includes various sensitivity levels and termination styles to accommodate different audio sensing requirements. The POM-2735P represents a standard sensitivity option within this lineup, utilizing a circular shape and top port location for consistent acoustic performance.
