CMC-4015-25T

Overview

The CMC-4015-25T is an omnidirectional electret condenser microphone manufactured by Same Sky. It operates within a voltage range of 3 V to 10 V and draws a supply current of 500 µA. The device features a sensitivity of -25 dB ±3 dB at 94 dB SPL, measured at 1 kHz. Its frequency response spans from 100 Hz to 20 kHz. The microphone utilizes solder pad termination for surface mount assembly.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Electret condenser transducer technology
• Surface mount solder pad termination

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates the tape and reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official certificates. Ensure the operating voltage aligns with the 3 V to 10 V specification range. Check for any recent PCN regarding terminal plating or material changes.

Selection Notes

Select this component when an omnidirectional pickup pattern is required for compact designs. The low supply current of 500 µA suits battery-powered applications. Verify that the 3 V to 10 V operating range matches the system power supply. Ensure the SMT solder pad footprint fits the PCB layout constraints.

Part Context

This model belongs to the CMC series of miniature microphones from Same Sky. It serves as a direct replacement for similar electret condenser microphones in space-constrained electronic assemblies. The series offers various sensitivity options and termination styles for different integration needs.

Replacement Considerations

Check pinout compatibility and physical dimensions against existing designs. Verify sensitivity tolerance (-25 dB ±3 dB) meets system requirements. Ensure the frequency response (100 Hz ~ 20 kHz) covers the target audio band.
