Microphones Procurement Notes

Verify the specific revision code and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the operating voltage and current requirements align with the target circuit design. Ensure mechanical dimensions fit the intended PCB footprint and enclosure constraints.

Microphones Selection Notes

Select this component when omnidirectional pickup is required for voice applications. Consider the -56 dB sensitivity and 100 Hz to 10 kHz bandwidth for standard voice frequencies. Evaluate the low supply current against battery life requirements. Compare physical dimensions against available board space.

Microphones Part Context

This microphone belongs to Knowles' line of analog electret condenser microphones designed for consumer electronics. It offers a balance of performance and size for voice-centric applications. The product is distinct from their capacitive MEMS or piezoelectric offerings.

Microphones Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's catalog. Verify that alternative components match the electrical specifications, particularly sensitivity and impedance. Ensure mechanical compatibility if space is constrained.
