EM-23056-000

Microphones Overview

The EM-23056-000 is an omnidirectional analog microphone manufactured by Knowles. It utilizes an electret condenser transducer type with a rectangular surface-mount package measuring 3.57mm x 3.57mm x 2.20mm maximum height. The device operates within a frequency range of 100 Hz to 5 kHz and requires a rated voltage of 1.3 VDC with a supply current of 50 µA. It features a sensitivity of -56dB ±1dB at 94dB SPL and an impedance of 4.4 kOhms. The component is RoHS compliant and designed for top-port pad termination.

Microphones Procurement Notes

Verify the specific suffix against official Knowles documentation, as variations exist in the EM series. Confirm that the required sensitivity tolerance and impedance match your circuit design before ordering. Ensure compatibility with standard surface-mount reflow processes given the small form factor.

Microphones Selection Notes

Select this component when an omnidirectional pickup pattern is required for general voice capture. The low power consumption and fixed sensitivity make it suitable for battery-operated portable electronics. Verify that the operating voltage aligns with the system's 1.3V requirement.
