POM-2746P

Microphones Overview

The POM-2746P is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern and a circular shape with a diameter of 0.236 inches (approximately 6 mm). The component operates on a supply voltage range of 2 V to 10 V and has a nominal impedance of 2.2 kOhms. Sensitivity is rated at -46 dB ±3 dB, with a signal-to-noise ratio of 60 dB. It utilizes PC pins for termination and is packaged in bulk.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture from all directions
• Electret condenser technology providing high sensitivity and low noise performance
• Standard through-hole PC pin termination for reliable circuit integration

Microphones Applications

Microphones Procurement Notes

Verify RoHS compliance status carefully as sources indicate non-compliance for this specific part number. Confirm that the required operating voltage range of 2 V to 10 V aligns with your circuit design constraints. Ensure PCB layout accommodates the specified PC pin spacing and physical dimensions for proper mechanical mounting.

Microphones Selection Notes

Select this component when an omnidirectional pickup pattern is required for general ambient sound capture. The wide operating voltage range offers flexibility in power supply design compared to fixed-voltage alternatives. Consider the 2.2 kOhm impedance match with preamplifier stages to optimize signal transfer efficiency and minimize loading effects.
