• Voice recognition systems

Microphones Procurement Notes

Verify the specific manufacturing lot and date code upon receipt to ensure compliance with current environmental standards. Confirm that the receiving environment meets the electrostatic discharge protection requirements suitable for electret condenser microphones. Ensure the supply voltage remains stable at 2.0V during operation to maintain specified sensitivity levels.

Microphones Selection Notes

Select this component when a small 4mm footprint is required for omnidirectional audio pickup. It is suitable for applications demanding low power consumption at 2.0V. Consider the -42dB sensitivity specification against ambient noise levels in the target environment. Verify mechanical mounting constraints for the cylindrical package.

Microphones Part Context

This microphone belongs to Mallory Sonalert's line of miniature audio transducers. It utilizes standard electret condenser technology commonly found in portable electronic devices. The 4mm diameter allows for integration into tight spaces where larger microphones cannot fit.
