Microphones Procurement Notes

Verify the specific suffix against official Knowles documentation to confirm exact sensitivity tolerances and port configurations. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Confirm RoHS compliance status matches the latest regulatory requirements before finalizing orders.

Microphones Selection Notes

Select this component when a compact form factor and low operating voltage are required for battery-powered applications. The standard impedance and sensitivity levels make it suitable for general-purpose voice capture where space constraints limit the use of larger microphone arrays. Evaluate mechanical mounting requirements to ensure compatibility with the target printed circuit board layout.

Microphones Part Context

This model belongs to the Knowles microphone portfolio, which specializes in miniature acoustic transducers. The EM series typically denotes specific packaging and sensitivity variants within their broader lineup of electret condenser microphones designed for modern consumer electronics.

Microphones Replacement Considerations

Consult official substitution lists for verified equivalents. Cross-reference physical dimensions and pinout configurations to ensure mechanical compatibility without modifying the existing circuit design.
