Overview
The CMC-6027-24T is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a circular shape with a diameter of 0.236 inches (6.00 mm) and a maximum height of 0.114 inches (2.90 mm). The device operates within a voltage range of 2 V to 10 V, drawing a supply current of 500 µA. It provides analog output with a sensitivity of -24 dB ±3 dB at 94 dB SPL and a signal-to-noise ratio of 70 dB. The frequency response spans from 50 Hz to 10 kHz, and the impedance is 2 kOhms. Termination is achieved via solder pads.
Feature Summary
- Omnidirectional acoustic design for uniform sound capture
- Electret condenser technology for analog audio signal conversion
- Compact cylindrical form factor suitable for space-constrained PCBs
- Top port location for direct sound exposure
Applications
- Consumer electronic audio input devices
- Voice recognition systems
- Portable recording equipment
- Telecommunication handsets
Procurement Notes
Verify the specific sensitivity suffix in the part number to ensure correct acoustic performance. Confirm that the solder pad termination matches the target PCB layout. Ensure the operating voltage aligns with the 2 V to 10 V specification. Check for RoHS compliance requirements if applicable to the final assembly.
Selection Notes
Select this component when an omnidirectional response is required for general audio pickup. The 2 kOhm impedance suits standard preamplifier inputs. Consider the physical dimensions of 6.00 mm diameter and 2.90 mm height for enclosure clearance. The top-port design necessitates unobstructed access to the sound source.
Part Context
This microphone belongs to the CMC series of electret condenser microphones from Same Sky. These components are designed for high-quality audio applications requiring reliable analog signal output. The series offers various sensitivity options and termination styles to accommodate different circuit designs and mechanical constraints.
Replacement Considerations
The CMC-6027-32L100 is a documented alternative within the same product family. Verify that the sensitivity difference (-32 dB vs -24 dB) meets system gain requirements. Ensure the lead wire termination of the replacement does not conflict with the solder pad design of the current board.
