Procurement Notes

Verify the manufacturer part number SMO05A-42/1316 against official BeStar Technologies documentation to confirm specifications. Ensure compatibility with the target circuit's voltage levels and impedance requirements. Check for specific ordering suffixes or tape-and-reel packaging options if required by automated assembly processes. Confirm lead times and availability through authorized distribution channels.

Selection Notes

Select this component when a low-profile, omnidirectional analog MEMS microphone is required for space-constrained designs. Consider the -42 dB sensitivity and 300 Ohm impedance for proper pre-amplifier matching. Evaluate the 1.5 V to 3.6 V operating range against the system power budget. The 200 µA supply current makes it suitable for energy-efficient applications.
