CMC-5044TF-A

Overview

The CMC-5044TF-A is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a 6.0 mm diameter and operates on a supply voltage range of 2 V to 10 V. The device provides analog output with a sensitivity of -44dB ±3dB at 94dB SPL. It has a frequency response spanning 100 Hz to 20 kHz and draws a maximum current of 500 µA. The component utilizes PC pin termination for PCB mounting and exhibits an impedance of 2.2 kOhms.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture from all directions
• Electret condenser technology providing analog audio signal output
• PC pin termination style enabling direct printed circuit board mounting

Applications

• Consumer electronic audio recording devices
• Voice recognition systems requiring omnidirectional pickup
• General-purpose analog audio sensing circuits

Procurement Notes

Verify the specific suffix 'TF-A' to confirm SMD/SMT or through-hole PC pin configuration, as variations exist within the CMC-5044 series. Ensure the operating voltage aligns with the 2 V to 10 V specification. Confirm impedance requirements match the 2.2 kOhm value. Check RoHS compliance status via official documentation before integration.

Selection Notes

Select this component when an omnidirectional pickup pattern is required for compact audio applications. The 6.0 mm form factor suits space-constrained designs. Verify that the 500 µA current draw fits the power budget. Ensure the host circuit can accommodate the 2 V to 10 V supply range and interfaces correctly with the analog output characteristics.

Part Context

This part belongs to the Same Sky CMC-5044 series of electret condenser microphones. The series offers various termination styles and package sizes. The CMC-5044TF-A specifically denotes the 6.0 mm diameter variant with PC pin terminals. It serves as an alternative to other omnidirectional microphones in similar size categories.

Replacement Considerations

Direct substitutes include the CMC-5044PF-A, which shares identical electrical specifications but differs in termination style. Verify mechanical footprint compatibility when swapping between PF and TF variants. Ensure acoustic performance metrics remain consistent for the target application.
