CMC-9745-37T

Overview

The CMC-9745-37T is an analog electret condenser microphone manufactured by Same Sky. It features a unidirectional polar pattern and solder pad termination for surface-mount integration. The device operates within a voltage range of 1.5 V to 9 V, drawing a supply current of 400 µA. Key electrical specifications include a sensitivity of -37dB ±3dB at 94dB SPL, an impedance of 2.2 kOhms, and a signal-to-noise ratio of 69dB. The frequency response spans from 100 Hz to 12 kHz. Physically, the component has a circular shape with a diameter of 0.382 inches (9.70 mm) and a maximum height of 0.185 inches (4.70 mm).

Feature Summary

Unidirectional acoustic design for focused sound capture.
Electret condenser technology providing high sensitivity.
Solder pad termination suitable for automated assembly.

Applications

Voice recognition systems
Consumer audio recording devices
Intercom units

Procurement Notes

Verify the manufacturer part number CMC-9745-37T against official Same Sky documentation to confirm exact sensitivity tolerances and voltage ratings. Ensure compatibility with the target PCB layout regarding the specified 0.382-inch diameter and 0.185-inch height constraints. Confirm that the solder pad termination method aligns with the manufacturing process requirements.

Selection Notes

Select this component when a compact, low-power unidirectional microphone is required for voice applications. The 2.2 kOhm impedance and 400 µA current draw are suitable for battery-operated portable electronics. Verify that the 1.5 V to 9 V operating range matches the system power supply architecture.

Part Context

This model belongs to the CMC series of microphones from Same Sky. It represents a specific variant within the broader family of electret condenser microphones designed for consumer electronics. The part number suffix typically denotes specific sensitivity or packaging variations within the standard CMC-9745 form factor.
