CMC-4012-40P

Overview

The CMC-4012-40P is a 4.0 mm omnidirectional electret condenser microphone designed for PCB mounting. It operates at a DC voltage of 2.0 V and features solder pin termination. The device exhibits a sensitivity of -40 dB and an impedance of 1 kOhm. Its frequency response spans from 100 Hz to 20 kHz, supporting analog audio signal capture in compact electronic assemblies.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound reception
• Electret condenser transducer technology for analog audio output
• PCB mount configuration with solder pin termination

Applications

• Consumer electronics audio input modules
• Portable communication devices
• General-purpose voice recording circuits

Procurement Notes

Verify the manufacturer designation as Same Sky (Formerly CUI Devices) against current corporate records. Confirm RoHS compliance status and specific datasheet revisions prior to integration. Ensure the 2.0 Vdc operating requirement aligns with target circuit power rails.

Selection Notes

Select this component when a low-profile, omnidirectional electret microphone is required for PCB assembly. The 4.0 mm diameter suits space-constrained designs. Verify that the 1 kOhm impedance matches the input requirements of the connected preamplifier or ADC stage.

Part Context

This part belongs to the Same Sky electret condenser microphone portfolio. It shares design characteristics with other models in the CMC series, such as the CMC-6015-47P, differing primarily in physical dimensions and sensitivity specifications.
