Microphones Procurement Notes

Verify the specific datasheet version for the MM033802-8 to confirm exact sensitivity tolerances and operating voltage limits. Ensure that the PCB layout accommodates the specified 3.76 mm x 2.95 mm footprint and 1.1 mm maximum height. Confirm compatibility with standard reflow soldering profiles for surface-mount technology components.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional analog microphone is required for space-constrained designs. The 190 µA supply current makes it suitable for battery-powered applications. Verify that the target application does not require digital interface capabilities, as this model provides only analog output signals.

Microphones Part Context

This part belongs to the DB Unlimited MM series of MEMS microphones. These components are designed for general-purpose audio capture in compact electronic devices. The series offers various form factors and electrical characteristics to suit different integration requirements.

Microphones Replacement Considerations

The MM033802-1 shares similar dimensions but differs in frequency range (70 Hz to 16 kHz) and impedance (300 Ohms). Verify pinout and acoustic performance compatibility before substitution.
