Microphones Procurement Notes

Verify the specific revision suffix and manufacturing date code against the latest official datasheet before procurement. Confirm that the target application environment meets the electrical operating limits defined in the specification sheet. Ensure compatibility with existing PCB footprint designs, as component availability may vary across distributors. Cross-reference part numbers carefully to avoid substitution errors with similar series components.

Microphones Selection Notes

Select this component when a low-profile, unidirectional microphone is required for voice or general audio recording in portable devices. Consider the 60 dB signal-to-noise ratio for standard clarity requirements. Evaluate the 2 V to 10 V supply range against the system's available power rails. Compare physical dimensions against enclosure constraints to ensure proper fitment within the device chassis.

Microphones Part Context

This model belongs to the MB series of microphones from Knowles, which focuses on miniaturized audio solutions. It shares design similarities with other MEMS and electret condensers in the portfolio but is distinct in its specific dimensional and electrical characteristics. The MB series is widely utilized in consumer electronics where size and acoustic performance are critical factors for integration.

Microphones Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative models such as MD6052USZ-1 only if electrical parameters and mechanical footprints match exactly. Consult official manufacturer channels for current obsolescence status and recommended replacements.
