Microphones Procurement Notes

Verify component availability status as the part may be subject to limited supply or end-of-life restrictions. Confirm RoHS compliance details through official manufacturer documentation prior to integration. Ensure design compatibility with specified operating voltage and impedance requirements during final validation.

Microphones Selection Notes

Select this component for applications requiring a low-profile, surface-mount microphone solution. Evaluate the -47 dB sensitivity against system noise floor requirements. Verify that the 680 Ohm impedance matches the preamplifier input specifications. Consider the 1.5 V operating voltage constraint when designing the power supply circuit.

Microphones Part Context

This microphone belongs to the DUM series from PUI Audio, designed for compact audio sensing applications. It serves as an alternative to through-hole microphones where space constraints necessitate surface-mount technology. The series provides standardized dimensions for easy PCB layout integration.

Microphones Replacement Considerations

Check for direct substitutes within the DUM series or compatible AUM models. Verify dimensional and electrical parameter equivalence before substitution.
