• General-purpose sound detection circuits

Microphones Procurement Notes

Verify the specific frequency response range required for your application, as sources cite either 50 Hz–16 kHz or 100 Hz–10 kHz. Confirm mechanical compatibility with the 6 mm diameter and 2.4 mm height dimensions. Ensure the PCB layout supports the specified solder pad termination style. Cross-reference the manufacturer part number POM-2244L-C33-R with official PUI Audio documentation to confirm electrical tolerances before finalizing the bill of materials.

Microphones Selection Notes

Select this component when an omnidirectional electret microphone with low voltage operation is required. The 2 VDC to 10 VDC supply range offers flexibility in system design. Consider the -44 dB sensitivity for standard voice-level applications. Verify that the 2.2 kohm impedance matches the input requirements of the connected amplifier or ADC stage. Ensure the physical footprint accommodates the 6 mm circular package.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio. The series includes various models with different heights and sensitivities, such as the POM-2242P and POM-2245L. These components are designed for compact electronic assemblies requiring reliable audio input capabilities.

Microphones Replacement Considerations

Direct substitutes include other PUI Audio POM series microphones with similar electrical characteristics, such as the POM-2242P-C33-R or POM-2245L-C33-R. Verify that any replacement maintains the same 6 mm diameter, solder pad termination, and compatible operating voltage range.
