CMC-6018-38T

Overview

The CMC-6018-38T is an omnidirectional analog electret condenser microphone manufactured by Same Sky. It features a circular shape with a diameter of 0.236 inches (6.00mm) and a maximum height of 0.079 inches (2.00mm). The device operates within a voltage range of 2 V to 10 V, drawing a supply current of 500 µA. Its frequency response spans from 100 Hz to 20 kHz, with a sensitivity of -38dB ±3dB at 94dB SPL and a signal-to-noise ratio of 58dB. The unit utilizes PC pin termination and has an impedance of 2.2 kOhms.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Analog output type suitable for standard audio processing circuits
• Compact cylindrical form factor with top port location

Applications

• Consumer electronic audio input devices
• Voice recognition systems
• General purpose sound detection modules

Procurement Notes

Verify the specific suffix against official documentation to confirm termination style and sensitivity tolerances. Ensure the selected variant matches the required PCB mounting configuration and electrical specifications for the target application circuit.

Selection Notes

Select this component when a compact, omnidirectional electret microphone with PC pin termination is required. Consider the 2V to 10V operating range and 500µA current draw during power budgeting. Verify that the 2.2kΩ impedance aligns with the input requirements of the connected amplifier or ADC stage.

Part Context

This part belongs to the CMC series of electret condenser microphones from Same Sky. The series offers various configurations in terms of size, sensitivity, and termination methods to accommodate different embedded audio design constraints and spatial limitations.

Replacement Considerations

Cross-reference with CMC-6018-38P for identical mechanical dimensions but differing termination types. Verify functional equivalence with other -38dB sensitivity omnidirectional microphones if pinout compatibility is not required.
