Microphones Procurement Notes

Verify the specific suffix code against official Knowles documentation to confirm exact electrical tolerances and port configurations. Ensure compatibility with existing PCB footprints regarding the 5.56 x 3.98 x 2.21 mm package dimensions. Confirm that the 1.3 V operating voltage aligns with the target system's power supply rails before integration.

Microphones Selection Notes

Select this component when ultra-small form factors are critical alongside standard omnidirectional performance. The low operating current supports battery-powered designs, while the fixed sensitivity ensures consistent signal levels. Evaluate mechanical mounting requirements for SMD/SMT assembly processes to ensure reliable solder joint formation during manufacturing.
