Microphones Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact pinout configuration before finalizing the schematic. Ensure the host circuit provides the required 2 V bias voltage within acceptable tolerance limits to maintain optimal sensitivity and noise performance characteristics during operation.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for space-constrained designs. The 4 mm diameter allows for discreet placement in small enclosures. Consider the 60 dB SNR for environments requiring clear voice capture with minimal background interference.

Microphones Part Context

This model belongs to the MO series of microphones manufactured by DB Unlimited. The series focuses on providing reliable electret condenser solutions for various audio input needs. The MO044002-1 specifically targets applications demanding a balance between compact physical dimensions and standard electrical interface requirements.

Microphones Replacement Considerations

Cross-reference with other 4 mm omnidirectional electret microphones if supply constraints exist. Verify that substitute parts match the 2 V operating voltage and 500 µA current draw to ensure compatibility with existing biasing circuits without modification.
