CMEJ-0733-42-L050

Overview

The CMEJ-0733-42-L050 is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a cylindrical housing with a diameter of 7.0 mm and utilizes wire lead termination for circuit integration. The device operates at a supply voltage of 2.0 Vdc and presents an impedance of 2.2 kΩ. Its sensitivity is specified as -42 dB ±3 dB relative to 1 V/Pa at 94 dB SPL, with a frequency response range spanning from 100 Hz to 10 kHz.

Feature Summary

Omnidirectional acoustic pickup pattern for uniform sound capture
Electret condenser transducer technology
Wire lead termination for flexible assembly

Applications

Consumer audio devices
Voice recognition systems
General purpose sound detection

Procurement Notes

Verify the specific suffix L050 against official Same Sky documentation to confirm wire length and termination specifications. Ensure the operating voltage requirements align with the 2.0 Vdc specification provided in the datasheet. Confirm RoHS compliance status through the manufacturer's current certification documents before finalizing procurement.

Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for compact electronic designs. The 2.0 Vdc operating voltage makes it suitable for battery-powered applications. Consider the 7.0 mm diameter and wire lead format for mechanical integration constraints within the target enclosure design.

Part Context

This part belongs to the Same Sky CMEJ series of electret condenser microphones. The series offers various form factors and electrical characteristics to support diverse audio input needs in portable electronics. The CMEJ-0733-42-L050 specifically addresses applications requiring standard omnidirectional performance with simple wiring interfaces.

Replacement Considerations

Cross-reference with other CMEJ series variants such as CMEJ-0629 or CMEJ-0627 if dimensional changes are permissible. Verify that alternative parts match the 2.0 Vdc supply voltage and 2.2 kΩ impedance requirements to ensure circuit compatibility without modification.
