Microphones Procurement Notes

Verify the specific revision level and packaging configuration directly with Knowles Electronics or authorized distributors before procurement. Confirm that the operating voltage and impedance parameters align with the target circuit design requirements. Ensure compliance with relevant regional environmental regulations such as RoHS standards applicable to the final assembly.

Microphones Selection Notes

Select this component when miniaturization is critical alongside reliable analog audio signal acquisition. Evaluate the trade-off between the 7.4 kHz upper frequency limit and application needs. Consider the 0.9 V minimum operating voltage for low-power battery-operated systems. Compare against other EM series variants if wider bandwidth or different mounting styles are required.
