Microphones Procurement Notes

Verify the specific datasheet version provided by Knowles or authorized distributors to confirm exact mechanical tolerances and electrical characteristics. Ensure compatibility with existing PCB layout constraints regarding pad size and soldering profiles. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog signal processing. Consider the 100 Hz to 4.8 kHz bandwidth limitation against application needs. Evaluate the 0.9 V to 1.6 V operating range against available power rails. Compare impedance and sensitivity specifications with other Knowles models if different acoustic performance is necessary.

Microphones Part Context

This model belongs to Knowles' portfolio of miniature microphones engineered for high reliability in small form factors. It utilizes condenser technology to convert acoustic pressure into electrical signals. The product line emphasizes integration ease for modern mobile and IoT devices where space and power efficiency are critical design parameters.

Microphones Replacement Considerations

Consult official Knowles documentation for direct pin-compatible substitutes. Verify that alternative components match the 0.9 V to 1.6 V supply range and 4.4 kOhm impedance. Ensure replacement parts maintain the same omnidirectional characteristic and frequency response profile.
