POM-3042P

Microphones Overview

The POM-3042P is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a 6 mm diameter and 3 mm depth cylindrical package with wire lead termination. The device operates on a supply voltage of 2 VDC and draws a maximum current of 500 µA. Key electrical parameters include a sensitivity of -42 dB ±3 dB, an impedance of 2.2 kohms, and a frequency response range spanning from 30 Hz to 15 kHz.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture
• Electret condenser transducer technology for analog audio output
• Compact cylindrical form factor suitable for space-constrained designs

Microphones Applications

• Consumer electronics audio input modules
• Industrial control panel voice interfaces
• Medical equipment monitoring systems

Microphones Procurement Notes

Verify the specific suffix designation when ordering, as variations such as POM-3042L-R or POM-3042P-C33-R exist within the same product family. Confirm that the required termination type matches the design requirements, as options include standard wire leads or solder pins. Ensure the operating voltage aligns with the 2 VDC specification provided in the official datasheet to guarantee proper biasing and performance.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for general-purpose audio sensing. The 2.2 kohm impedance and -42 dB sensitivity are suitable for applications requiring moderate gain stages. Consider the physical dimensions of 6 mm diameter and 3 mm depth against available board space. Verify environmental ratings if exposure to moisture or dust is anticipated, as standard versions may not offer high IP protection levels.

Microphones Part Context

The POM series represents PUI Audio's line of compact electret microphones designed for integration into various electronic devices. This specific model belongs to the standard product catalog, distinguishing it from custom or special order audio solutions. It serves as a fundamental audio input component for manufacturers developing devices that require reliable voice or ambient sound detection capabilities.

Microphones Replacement Considerations

Direct substitutes within the POM series include POM-3042L-R and POM-3042P-C33-R. Note that these variants may differ in termination style, such as solder pins versus wire leads, or sensitivity specifications. Cross-referencing the exact mechanical footprint and electrical characteristics is essential before swapping components.
