Microphones Procurement Notes

Verify the specific suffix C09 against official Knowles documentation to confirm exact termination and packaging details. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm RoHS compliance status through current manufacturer declarations before integration into regulated products.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for compact audio applications. The fixed 1.3 V operating voltage and specific sensitivity level must align with the target circuit's biasing requirements. Compare impedance characteristics against pre-amplifier inputs to ensure proper signal matching.

Microphones Part Context

This microphone belongs to the EK/EY series of audio devices produced by Knowles. The series is designed for general-purpose audio sensing applications requiring reliable performance in small form factors. It serves as a standard solution for integrating voice capture capabilities into modern electronic assemblies.

Microphones Replacement Considerations

EK-27263-C05 is a documented variant within the same series offering identical physical dimensions and core electrical characteristics. Verify pinout and sensitivity tolerances before substitution.
