Microphones Procurement Notes

Verify the specific datasheet version for the POM-2744P-C33-R to confirm exact dimensional tolerances and sensitivity bins. Ensure the application circuit provides the required 500 µA bias current within the specified voltage range. Confirm that the solder pin termination method aligns with the target PCB assembly process. Cross-reference the manufacturer's latest documentation for any updates regarding RoHS compliance or material composition changes.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for general-purpose voice capture. The 2.7 mm diameter allows integration into tight spaces where larger microphones cannot fit. The wide voltage tolerance simplifies power supply design across different system architectures. Consider the -44 dB sensitivity for environments with moderate ambient noise levels requiring standard gain amplification stages.

Microphones Part Context

This part belongs to the PUI Audio POM series of electret condenser microphones. The series offers various sizes and impedance options tailored for different audio fidelity and spatial requirements. PUI Audio specializes in custom and standard audio components for industrial, medical, and consumer markets, providing reliable transducer solutions for diverse acoustic sensing needs.

Microphones Replacement Considerations

The POM-2740P-C33-R is a similar omnidirectional microphone but features a larger 6 mm diameter. Verify if the increased physical size is acceptable for the enclosure. Both parts share comparable electrical characteristics such as 2.2 kΩ impedance and similar sensitivity ranges, facilitating potential functional substitution if mechanical constraints allow.
