PMO-4530PN-47UQ

Microphones Overview

The PMO-4530PN-47UQ is an electret condenser analog microphone manufactured by Mallory Sonalert Products Inc. It features an omnidirectional pickup pattern and utilizes PC pin termination for circuit integration. The device operates with a supply voltage (Vcc) of 2.0V and exhibits a maximum impedance of 2.2kΩ at 1kHz when loaded with a 2.2kΩ resistor. Its sensitivity range is specified as -47 ± 3 dB RL, referenced to 1 kHz 0 dB = 1 v/Pa. The physical dimensions are compact, measuring 4.5mm by 3.0mm.

Microphones Procurement Notes

Verify the specific sensitivity tolerance (-47 ± 3 dB) and operating voltage requirements (2.0V Vcc) against your circuit design specifications. Confirm that the PC pin termination style matches your PCB footprint and assembly process. Ensure the maximum impedance specification (2.2kΩ at 1kHz) aligns with your pre-amplifier input characteristics to maintain signal integrity.

Microphones Selection Notes

Select this component when an omnidirectional response is required in a minimal footprint application. The low operating voltage of 2.0V makes it suitable for battery-powered devices. Consider the analog nature of the output and the need for appropriate biasing circuits. The PC pin configuration dictates the mounting method on the printed circuit board.
