CMC-5044PF-A

Overview

The CMC-5044PF-A is an analog omnidirectional electret condenser microphone manufactured by Same Sky. It operates within a voltage range of 2 V to 10 V and draws a supply current of 500 µA. The device features a frequency response spanning from 100 Hz to 20 kHz with a sensitivity of -44 dB ±3 dB at 94 dB SPL. It utilizes PC pin terminals for connection and has an impedance of 2.2 kOhms. The physical dimensions include a diameter of 6.00 mm and a maximum height of 5.20 mm.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Analog output signal generation via electret condenser technology
• Standard PC pin terminal configuration for board integration

Applications

• General purpose audio input devices
• Consumer electronic voice recording modules
• Voice activated control systems

Procurement Notes

Verify the specific sensitivity tolerance and impedance values against the latest manufacturer datasheet prior to implementation. Confirm that the operating voltage range aligns with the target circuit power supply specifications. Ensure mechanical clearance accommodates the specified diameter and height constraints during PCB layout planning.

Selection Notes

Select this component when an omnidirectional pickup pattern is required for ambient sound detection or voice input. The standard 2.2 kOhm impedance and 500 µA current draw suit low-power analog audio circuits. Consider the fixed PC pin termination method for through-hole assembly processes rather than surface mount requirements.

Part Context

This microphone belongs to the analog electret condenser category produced by Same Sky, formerly known as CUI Devices. It serves as a standard transducer solution for converting acoustic pressure into electrical signals. The product line focuses on reliable audio sensing components for mass-market electronics requiring consistent performance across a broad frequency spectrum.
