Microphones Procurement Notes

Verify the specific suffix against official Knowles documentation to confirm exact electrical tolerances and packaging details. Confirm availability status as distribution channels may vary. Ensure compatibility with existing PCB footprints and soldering profiles before integration into production designs.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for space-constrained designs. The 3 V operating voltage and analog output are suitable for standard audio interfaces. Consider the 100 Hz to 10 kHz frequency range to ensure it meets the specific acoustic requirements of the target application.

Microphones Part Context

This part belongs to the Knowles FG-23742 series of miniature microphones. The series offers various configurations including undamped, screen damped, and internally damped responses. These variants allow designers to tailor acoustic performance characteristics such as frequency response and sensitivity to specific product needs.

Microphones Replacement Considerations

Direct substitutes within the same series include models like FG-23742-C05 and FG-23742-D65. Verify that alternative suffixes match the required operating voltage, sensitivity tolerance, and damping characteristics before substitution.
