CMR-4015-44-SP

Overview

The CMR-4015-44-SP is an electret condenser microphone manufactured by Same Sky. It features a compact rectangular form factor measuring 4 mm in diameter and 1.5 mm in depth. The device operates on a 1 Vdc supply voltage with a rated current of 500 uA. It provides a sensitivity of -44 dB and utilizes SMD/SMT solder pads for termination. This noise-canceling microphone is designed for integration into audio input circuits requiring low-profile surface-mount assembly.

Feature Summary

Noise-canceling design for improved signal clarity
Low-profile surface-mount construction
Electret condenser transducer technology

Applications

Consumer electronics audio input
Portable communication devices

Procurement Notes

Verify the specific package type and termination style against the official datasheet before procurement. Confirm that the operating voltage and current requirements align with the target circuit design. Ensure compatibility with standard surface-mount assembly processes. Check for any specific handling precautions related to the electret element during manufacturing.

Selection Notes

Select this component when a low-profile, noise-canceling microphone is required for space-constrained applications. Consider the 1 Vdc operating voltage and 500 uA current draw for power budget calculations. Evaluate the -44 dB sensitivity against the required acoustic input levels. Ensure the SMD/SMT termination method matches the PCB layout and assembly capabilities.
