CMC-6022-42P

Overview

The CMC-6022-42P is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a compact cylindrical design with a 6.0 mm diameter and a maximum height of 2.40 mm, suitable for space-constrained PCB mounting. The device operates at a rated voltage of 2 VDC and draws a supply current of 500 µA. Key electrical specifications include a sensitivity of -42 dB ±3 dB referenced to 1 V/Pa at 94 dB SPL, an impedance of 2.2 kΩ, and a frequency response range of 100 Hz to 20 kHz.

Feature Summary

• Omnidirectional acoustic pattern ensures uniform sound capture from all directions
• Compact surface-mount form factor designed for integration into portable electronics
• Low power consumption suitable for battery-operated devices

Applications

• Portable consumer audio equipment
• Voice recognition modules
• Handheld communication devices

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout configuration and sensitivity tolerance. Ensure that the procurement channel provides valid RoHS compliance documentation consistent with the component's environmental standards. Cross-reference the part number with the latest Same Sky product change notifications to account for any manufacturing updates or material substitutions.

Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for general voice pickup applications. The fixed 2.2 kΩ impedance and 2 VDC operating voltage define the necessary biasing circuitry requirements. Designers must ensure the enclosure allows for unobstructed acoustic access to the top port while maintaining the specified dimensional constraints.

Part Context

This microphone belongs to the CMC series of miniature electret condenser microphones produced by Same Sky. The series is engineered for high-volume consumer electronics where small footprint and reliable analog audio output are critical. It serves as a standard solution for basic voice input functions in modern digital devices.

Replacement Considerations

Direct substitutes within the same series may include models with different sensitivity ratings such as the CMC-6022-38T. Verify that alternative part numbers maintain compatibility with the existing PCB footprint and biasing network before implementation.
