POM-2242P-C33-R

Microphones Overview

The POM-2242P-C33-R is an omnidirectional electret microphone manufactured by PUI Audio. It features a cylindrical housing with a diameter of 6 mm and a length of 6 mm, while the depth measures 2.2 mm. The device operates at a voltage of 2 V and presents an impedance of 2.2 kOhms. Its sensitivity is rated at -46 dB. Electrical connections are established via solder pins.

Microphones Feature Summary

• Omnidirectional acoustic response for uniform sound capture from all directions
• Compact cylindrical form factor designed for space-constrained installations
• Direct solder pin termination for straightforward PCB integration

Microphones Applications

• Consumer electronic audio input devices
• Portable communication equipment
• General-purpose voice recording modules

Microphones Procurement Notes

Verify the specific suffix C33 against the manufacturer's current datasheet to confirm exact mechanical tolerances and electrical characteristics. Ensure the solder pin configuration matches the target PCB footprint design. Confirm RoHS compliance status through official documentation prior to final procurement decisions.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for compact assemblies. The 2.2 kOhm impedance and 2 V operating voltage define the necessary biasing circuitry requirements. Evaluate the -46 dB sensitivity against ambient noise levels in the intended application environment.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio. The series typically offers various impedance and sensitivity options within standardized physical dimensions. The POM designation indicates a specific line of omnidirectional electret condenser microphones designed for general audio applications.

Microphones Replacement Considerations

Cross-reference with other POM series variants such as POM-2245L-C33-R or POM-2246P-2-R if sensitivity adjustments are needed. Verify that substitute parts maintain the same 6 mm diameter and solder pin interface to ensure mechanical compatibility without redesigning the mounting structure.
