Microphones Procurement Notes

Verify the specific suffix (e.g., -C33-R) when ordering, as it may denote packaging or tape-and-reel variations not explicitly detailed in basic part number listings. Confirm RoHS compliance status through the official datasheet before finalizing procurement. Ensure the operating voltage requirements match your system's 3 VDC supply rail to prevent performance degradation.

Microphones Selection Notes

Select this component for applications requiring low-profile audio sensing where omnidirectional coverage is necessary. The 2.2 kOhm impedance is suitable for standard pre-amplifier inputs. Consider the physical dimensions of 6 mm x 2.2 mm for tight space constraints. Validate that the -44 dB sensitivity meets the signal-to-noise ratio requirements of the target application environment.

Microphones Part Context

This microphone belongs to the POM series of audio sensors produced by PUI Audio, Inc., a manufacturer specializing in audio components for industrial and consumer markets. The series includes various sizes and configurations designed for integration into electronic devices requiring reliable sound detection. PUI Audio has established expertise in piezo and microphone technologies since its founding in 1973.

Microphones Replacement Considerations

The POM-2244L-C33-R is a documented variant within the same product family. Verify if the suffix indicates a specific packaging format or minor manufacturing revision. Cross-reference impedance and sensitivity values with alternative models to ensure functional compatibility in existing designs.
