Microphones Procurement Notes

Verify specific sensitivity tolerances (-44dB vs -46dB) and frequency upper limits (15kHz vs 19kHz) against the latest manufacturer datasheet prior to procurement. Confirm package dimensions and pinout compatibility with PCB layout requirements. Ensure voltage supply constraints align with the specified 1.3V to 10V operating range for reliable performance in the target application environment.

Microphones Selection Notes

Select this component when an omnidirectional electret condenser microphone is required for space-constrained applications due to its rectangular SMD footprint. Consider the 2.2 kOhm impedance and analog output characteristics for interface circuit design. Evaluate the 60dB SNR specification against background noise levels in the intended deployment environment to ensure adequate audio clarity.
