CMEJ-0629-36-L050

Overview

The CMEJ-0629-36-L050 is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a cylindrical design with a diameter of 6.0 mm and a depth of 2.7 mm. The component operates at a DC voltage of 4.5 V and draws a current of 500 uA. It has an impedance of 2.2 kOhms and a sensitivity of -36 dB. The microphone utilizes wire leads for termination and covers a frequency response range from 100 Hz to 10 kHz.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture
• Electret condenser technology for reliable audio signal conversion
• Compact cylindrical housing suitable for space-constrained designs
• Wire lead termination for flexible integration

Applications

• Consumer electronic audio input devices
• Voice recognition systems
• Portable recording equipment
• Telecommunication handsets

Procurement Notes

Verify the specific ordering suffix L050 to confirm wire lead length and termination style, as variations exist within the series. Ensure the operating circuit provides the required 4.5 Vdc supply and matches the 2.2 kOhm impedance load. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when an omnidirectional polar pattern is required for general voice pickup applications. The 6.0 mm diameter allows for integration into small enclosures where larger microphones cannot fit. Consider the 4.5 V operating voltage requirement against available board power rails. The wire lead format offers flexibility for custom assembly compared to surface-mount alternatives.

Part Context

This microphone belongs to the CMEJ series of electret condenser microphones produced by Same Sky, formerly known as CUI Devices. The series offers various configurations differing in size, sensitivity, and termination methods. This specific model represents a standard omnidirectional option designed for general-purpose audio sensing tasks in commercial electronics.

Replacement Considerations

Cross-reference with other CMEJ series variants such as CMEJ-0627-42-P if PCB mounting is preferred over wire leads. Verify that substitute parts maintain compatible impedance and sensitivity levels to ensure consistent audio performance without requiring significant circuit redesign.
