TNM-3054L-R

Overview

The TNM-3054L-R is an electret condenser microphone manufactured by PUI Audio, Inc. It features a circular shape with a diameter of 4.5 mm and a maximum height of 1.20 mm. The device operates within a frequency range of 30 Hz to 15 kHz and provides analog output. Key electrical specifications include a sensitivity of -45 dB ±3 dB and a signal-to-noise ratio of 55 dB. It requires a supply voltage between 2 V and 10 V and utilizes solder pad termination.

Feature Summary

• Compact individual port design simplifies signal routing
• Noise cancelling capability for clear voice capture
• Electret condenser technology for analog audio output

Applications

• Voice capture in consumer electronics
• Audio input for industrial controls
• Communication devices requiring compact form factors

Procurement Notes

Verify the specific datasheet version for the TNM-3054L-R to confirm exact sensitivity tolerances and operating voltage ranges. Ensure compatibility with the target circuit's impedance requirements. Confirm that the solder pad termination method aligns with the PCB layout design. Cross-reference the physical dimensions against the enclosure constraints to ensure proper fitment during assembly.

Selection Notes

Select this component when a low-profile, noise-cancelling electret microphone is required for analog audio applications. The 4.5 mm diameter suits space-constrained designs. Verify that the system power supply falls within the 2 V to 10 V range. Consider the -45 dB sensitivity for appropriate gain staging in the pre-amplifier stage. Ensure the operating temperature range meets environmental requirements.
