Microphones Procurement Notes

Verify the specific termination style and package dimensions against the official datasheet before procurement. Confirm that the operating supply voltage and bias current requirements align with the target circuit design. Ensure compliance with relevant environmental standards such as RoHS if required by the application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general-purpose audio sensing. The 3 V operating voltage suits low-power embedded systems. Consider the physical footprint of 9.7 mm diameter and 4.5 mm depth for enclosure constraints. The solder pin termination is suitable for standard PCB assembly processes requiring through-hole mounting.

Microphones Part Context

This microphone belongs to the MO series produced by DB Unlimited, specializing in audio devices. The series includes various electret condenser microphones designed for different mounting styles and acoustic requirements. This specific model represents a standard through-hole option within their broader portfolio of audio transducers.

Microphones Replacement Considerations

Check for direct substitutes within the same manufacturer series that match the 9.7 mm diameter and 3 V operation. Verify compatibility of the 2.2 kOhm impedance and -58 dBA sensitivity with existing amplifier stages. Ensure the replacement maintains the omnidirectional characteristic and through-hole termination style.
