Microphones Procurement Notes

Verify the specific suffix KDQ against the manufacturer's official datasheet to confirm pin configuration and tolerance specifications. Ensure that the operating voltage limits of 1 V to 10 V align with your system's power supply rails. Confirm that the PC pin termination method matches your printed circuit board layout requirements before finalizing procurement.

Microphones Selection Notes

Select this component when an omnidirectional response is required for accurate ambient sound capture. The low current consumption of 0.5 mA makes it suitable for battery-powered applications. Its small physical footprint allows integration into miniaturized devices where larger microphones cannot fit. Verify compatibility with your analog front-end circuitry regarding impedance and sensitivity levels.

Microphones Part Context

This microphone belongs to the PMO series of analog electret condenser microphones produced by Mallory Sonalert Products Inc. The series is characterized by its compact size and reliability in various audio sensing applications. The PMO-4015PN-42KDQ specifically denotes the -42 dB sensitivity variant with PC pin termination, distinguishing it from other models in the lineup with different sensitivities or mounting styles.

Microphones Replacement Considerations

Consult the official Mallory Sonalert replacement guide for verified substitutes. Ensure any alternative maintains the same -42 dB sensitivity and 50 Hz to 12 kHz frequency response. Verify that the replacement part supports the 1 V to 10 V operating voltage range and utilizes compatible PC pin termination for seamless integration.
