Microphones Procurement Notes

Verify the specific suffix codes on the component marking against official Knowles documentation to confirm exact sensitivity bins and lead time classifications. Ensure that the ordering part number matches the required acoustic performance specifications for your design. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards and material compositions.

Microphones Selection Notes

Select this component when a small form factor and omnidirectional pickup are required for voice applications. Consider the operating voltage constraints and required sensitivity levels relative to the host amplifier's input noise floor. Evaluate the mechanical mounting requirements and acoustic porting needs to ensure optimal performance within the final enclosure design.

Microphones Part Context

This microphone belongs to the FG series of miniature electret condenser microphones manufactured by Knowles. The series is widely utilized in portable electronics due to its small footprint and reliable acoustic performance.
