Microphones Procurement Notes

Verify the specific suffix 'R' in the ordering code PUM-3546L-R against official datasheets to confirm packaging details. Confirm RoHS compliance status directly from the manufacturer's documentation before integration. Ensure the 1.5 V operating voltage aligns with the target circuit design requirements.

Microphones Selection Notes

Select this model when a low-profile, omnidirectional microphone is required for space-constrained designs. The 2.2 kOhm impedance and -38 dB sensitivity are suitable for general-purpose voice capture applications. Verify that the solder pin termination method matches the printed circuit board layout constraints.

Microphones Part Context

This component belongs to the PUM series of microphones produced by PUI Audio. The manufacturer specializes in audio devices including transducers and speakers. This specific part represents a standard electret microphone option within their broader portfolio of audio solutions.

Microphones Replacement Considerations

The POM-3546P-R shares identical acoustic specifications but uses SMD/SMT termination instead of solder pins.
