Microphones Procurement Notes

Verify the specific suffix requirements against the manufacturer's official datasheet to ensure correct packaging and terminal configuration. Confirm that the 1V to 10V operating voltage range aligns with the target circuit design. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the PC pin pitch matches the printed circuit board layout specifications.

Microphones Selection Notes

Select this component when an omnidirectional response is required within the 50 Hz to 10 kHz bandwidth. The -38dB sensitivity offers a balanced output level for standard analog processing circuits. Consider the 500 µA supply current for battery-powered applications where power efficiency is critical. The 2.2 kOhm impedance should be compatible with the input stage of the connected amplifier or microcontroller.

Microphones Part Context

This microphone belongs to Soberton Inc.'s line of electret condenser microphones designed for general-purpose audio sensing. The series emphasizes compact form factors and reliable analog performance for embedded audio applications. It serves as a standard solution for voice detection in consumer electronics where size and cost are primary design drivers.

Microphones Replacement Considerations

Direct substitutes may include other 4mm omnidirectional electret microphones with similar -38dB sensitivity and 2.2 kOhm impedance.
