CMC-4015-40L170

Overview

The CMC-4015-40L170 is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a top port design with wire lead termination and operates within a voltage range of 2 V to 10 VDC, drawing a supply current of 500 µA. The device provides a sensitivity of -40 dB ±3 dB at 94 dB SPL and maintains an impedance of 2.2 kΩ. Its frequency response spans from 100 Hz to 20 kHz, ensuring accurate audio capture across the audible spectrum.

Feature Summary

• IP65 rated enclosure for protection against dust and water resistance
• Omnidirectional acoustic pattern for uniform sound pickup
• Top port configuration facilitating direct sound exposure

Applications

• Consumer electronics requiring environmental durability
• Voice recognition systems in humid conditions
• Portable audio recording devices

Procurement Notes

Verify the specific datasheet version for the CMC-4015-40L170 to confirm exact dimensional tolerances and electrical characteristics prior to integration. Ensure that the host circuitry supports the required 2 V to 10 VDC operating range and 500 µA current draw. Confirm that the IP65 rating aligns with the intended environmental exposure requirements of the final assembly.

Selection Notes

Select this component when an omnidirectional electret microphone with high environmental protection is required. The wide operating voltage range allows flexibility in power supply design. The IP65 rating makes it suitable for applications exposed to moisture or dust where standard microphones might fail. Consider the wire lead termination method for PCB layout constraints.

Part Context

This part belongs to the Same Sky CMC series of electret condenser microphones. These components are designed for general-purpose audio sensing applications. The series offers various sensitivity and package options to suit different acoustic needs while maintaining consistent quality standards established by the manufacturer.

Replacement Considerations

Direct replacements must match the 4.0 mm diameter, omnidirectional pattern, and IP65 rating. Verify compatibility with the existing bias voltage and current requirements. Alternative parts should offer similar frequency response and sensitivity levels to maintain system performance.
