CMC-4015-40T

Overview

The CMC-4015-40T is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a compact cylindrical design with a diameter of 4 mm and a depth of 1.5 mm. The device operates on a voltage range of 2 V to 10 V and draws a current of 500 µA. It provides a sensitivity of -40 dB ±3 dB at 94 dB SPL and has an impedance of 2.2 kΩ. The frequency response spans from 100 Hz to 20 kHz, making it suitable for general audio capture applications.

Feature Summary

• Omnidirectional acoustic pattern for uniform sound pickup
• Electret condenser technology for analog audio output
• Compact surface-mount form factor for space-constrained designs

Applications

• Consumer electronics audio input modules
• Portable recording devices
• Voice recognition systems

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm packaging type and availability status. Ensure compatibility with existing PCB footprints and soldering profiles. Confirm RoHS compliance requirements match project specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog signal processing. The 2.2 kΩ impedance and 500 µA current draw are standard for many pre-amplifier circuits. Consider the 100 Hz to 20 kHz frequency range against specific voice or environmental noise filtering needs.

Part Context

This part belongs to the Same Sky CMC series of electret microphones. It shares physical dimensions with other variants in the line but differs in electrical characteristics such as sensitivity and impedance. The series is designed for integration into various consumer electronic devices requiring reliable audio capture capabilities.

Replacement Considerations

Direct substitutes may include other 4mm omnidirectional electret microphones with similar sensitivity and impedance. Verify pinout compatibility and mounting hole alignment. Check if alternative parts offer improved frequency response or lower noise figures for specific application requirements.
