Microphones Procurement Notes

Verify the specific revision status and manufacturing date code upon order confirmation, as electronic components are subject to change. Confirm that the matched set requirement aligns with your assembly process. Ensure compatibility with standard surface mount reflow profiles if applicable. Check for any specific handling instructions regarding electrostatic discharge protection during storage and installation.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog signal processing. The matched set specification is critical for multi-microphone arrays where phase and sensitivity matching are necessary. Consider the side-port orientation relative to the enclosure design to ensure proper acoustic coupling. Verify that the 500 Hz to 4 kHz bandwidth meets the target application's voice frequency requirements.

Microphones Part Context

This part belongs to Knowles' line of electret condenser microphones, which are widely used in portable electronics. The EM series typically offers compact form factors suitable for space-constrained designs. As a matched set, it addresses the variability inherent in mass-produced acoustic sensors, providing engineers with predictable performance characteristics without individual calibration.

Microphones Replacement Considerations

Direct replacements must match the electrical specifications, particularly the 930 mV rating and frequency response. Ensure substitute parts also offer omnidirectional patterns and compatible solder pad terminations. If using a single unit instead of a matched set, verify that sensitivity variation is acceptable for the application.
