CMC-3015-44L100

Overview

The CMC-3015-44L100 is an omnidirectional analog electret condenser microphone manufactured by Same Sky. It operates within a frequency range of 100 Hz to 20 kHz and requires a supply voltage between 2 V and 10 V with a typical current consumption of 500 µA. The device features a sensitivity of -44dB ±2dB at 94dB SPL and an impedance of 2.2 kOhms. Physically, it has a cylindrical shape with a diameter of 3 mm and a height of 1.5 mm, utilizing wire leads for termination.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser transducer technology providing stable analog audio output
• Wire lead termination facilitating direct connection to circuit boards or harnesses

Applications

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

Procurement Notes

Verify the specific suffix L100 to confirm wire lead configuration and length requirements. Ensure the operating environment supports the standard IP rating as no waterproofing is explicitly stated for this variant. Confirm RoHS3 compliance status if required by local regulations. Cross-reference the manufacturer part number with distributor codes to avoid sourcing errors during procurement.

Selection Notes

Select this component when a compact, low-profile microphone with wire leads is required. It is suitable for applications needing a wide frequency response up to 20 kHz. Consider the 2 V to 10 V operating range for power supply compatibility. Evaluate the physical dimensions against available space constraints in the final assembly design.

Part Context

This microphone belongs to the CMC series of electret condenser microphones from Same Sky. The series offers various form factors including surface mount and through-hole options. This specific model emphasizes a small footprint with wire connections, distinguishing it from solder pad or pin-mount variants within the broader product family.

Replacement Considerations

Direct substitutes may include other omnidirectional electret microphones with similar dimensions and electrical characteristics. Verify sensitivity, impedance, and voltage requirements before substitution. Alternative models from the same manufacturer with different termination types may require mechanical adaptation.
