Microphones Procurement Notes

Verify the specific suffix C54 against the official Knowles datasheet to confirm exact sensitivity tolerance and acoustic port configuration. Ensure compatibility with standard reflow soldering profiles for SMD components. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Microphones Selection Notes

Select this component when a small form factor is required alongside omnidirectional coverage. Compare sensitivity levels against alternative models if higher output voltage is needed. Verify that the 1.3 V operating voltage aligns with the target system's power rails and that the 4.4 kohm impedance matches the preamplifier input requirements.

Microphones Part Context

This microphone belongs to the Knowles portfolio of miniature audio sensors. It utilizes electret condenser technology to convert acoustic signals into electrical outputs. The series is engineered for high reliability in mass-produced electronic devices where size constraints are critical.

Microphones Replacement Considerations

Consult the official Knowles replacement guide for direct equivalents. Verify pinout compatibility and acoustic performance metrics before substituting with other omnidirectional SMD microphones.
