Microphones Procurement Notes

Verify the specific suffix variant required, such as PUM-5250L-C3310-R, as suffixes may denote distinct packaging or minor specification variations not detailed in the base model description. Confirm RoHS compliance status through the official manufacturer datasheet prior to final procurement. Ensure the selected component matches the required operating voltage and sensitivity parameters for the target application circuit design.

Microphones Selection Notes

Select this component when a compact, low-power unidirectional microphone is required for embedded audio applications. The 6 mm form factor suits space-constrained designs. Verify that the host circuit can provide the necessary 2V to 10V bias voltage and accommodate the 500 µA quiescent current draw. Ensure the 2.2 kOhm impedance is compatible with the downstream amplifier input stage.
