Microphones Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact mechanical or electrical variations. Ensure compatibility with existing PCB footprint dimensions and soldering profiles. Confirm RoHS compliance status as indicated in the specific datasheet version prior to integration into final assemblies.

Microphones Selection Notes

Select this component when an omnidirectional response is required within a compact form factor. The 2.2kΩ impedance and 2V operating voltage define the biasing requirements for the preamplifier stage. Evaluate the 60dB SNR against the ambient noise environment of the target application to ensure adequate audio fidelity.

Microphones Part Context

This microphone belongs to the EM series produced by Soberton Inc., designed for compact audio sensing applications. The model represents a standard electret condenser variant optimized for cost-effective integration into portable electronics and voice-enabled devices requiring reliable analog audio conversion.

Microphones Replacement Considerations

Cross-reference with other Soberton EM series microphones for pin-compatible alternatives. Verify that substitute components match the 4.50mm diameter constraint and 2.2kΩ impedance specification to maintain circuit performance without redesign.
