Microphones Procurement Notes

Verify the obsolete status indicated by DigiKey before finalizing procurement plans. Confirm current availability through authorized distributors or alternative sourcing channels. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Validate that the -49dB sensitivity meets system requirements.

Microphones Selection Notes

Select this component for applications requiring low-profile omnidirectional sound capture. The 2.2 kOhm impedance matches standard preamplifier inputs. Consider the 3.70mm height constraint for tight enclosure designs. Evaluate if the analog output format aligns with downstream processing circuits.

Microphones Part Context
