CMC-6027-42T

Overview

The CMC-6027-42T is an 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 from 100 Hz to 20 kHz with a sensitivity of -42dB ±3dB at 94dB SPL. It has a nominal impedance of 2 kOhms and a signal-to-noise ratio of 70dB. The component utilizes solder pad termination and measures 6.0 mm in diameter.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Electret condenser technology for analog audio signal conversion
• Solder pad termination for direct PCB integration

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly, as this differs from bulk or leaded variants. Confirm the operating voltage requirements match the target circuit design, noting the 2V to 10V range. Ensure the 6mm diameter footprint aligns with the mechanical constraints of the final enclosure. Cross-reference the manufacturer's latest datasheet for any recent pinout or material compliance updates.

Selection Notes

Select this model when an omnidirectional pickup pattern is necessary for broad sound coverage. The -42dB sensitivity offers a balance between high-output and low-noise performance suitable for general voice applications. Consider the 2kOhm impedance for compatibility with standard preamplifier inputs. The compact 6mm form factor allows for integration into space-constrained portable devices compared to larger industrial microphones.

Part Context

This component belongs to the CMC series of electret condenser microphones from Same Sky. These devices are designed to convert acoustic energy into electrical signals for various audio processing applications. The series includes various sensitivity levels and package types, with the CMC-6027-42T specifically offering a -42dB sensitivity rating and surface-mount solder pad configuration.

Replacement Considerations

Direct substitutes include the CMC-6027-32T for higher sensitivity (-32dB) and the CMC-6027-42L100 for leaded termination instead of solder pads. Verify that alternative parts maintain the same 6mm diameter and 2kOhm impedance to ensure mechanical and electrical compatibility without redesigning the host circuit board.
