Microphones Procurement Notes

Verify the specific suffix requirements when ordering, as variants such as PUM-3046L-R may exist with different packaging or termination specifications. Confirm that the application circuit supports the required 500 µA bias current and 2.2 kohm impedance load. Ensure the mechanical mounting space accommodates the 6 mm diameter and 3 mm depth constraints. Cross-reference datasheets for environmental ratings if operating in extreme temperatures.

Microphones Selection Notes

Select this component for applications requiring a compact, low-power analog microphone with a unidirectional response. It is suitable for designs needing a wide supply voltage tolerance, accommodating both 3.3V and 5V logic systems without additional regulation. Consider the -46 dB sensitivity for moderate noise environments. Evaluate mechanical integration needs against the small form factor.
