TOM-3046L

Overview

The TOM-3046L is an analog omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a sensitivity of -46 dB and operates within a frequency range of 30 Hz to 15 kHz. The device requires a supply voltage between 2 V and 10 V and utilizes solder pads for termination. Its compact design includes a diameter of approximately 4.5 mm (0.177 inches), making it suitable for space-constrained audio input applications.

Feature Summary

Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
Electret condenser transducer technology for stable analog signal output
Low operating voltage compatibility with standard digital logic interfaces

Applications

Consumer electronics audio input modules
Portable communication devices
Industrial voice recognition systems

Procurement Notes

Verify the specific suffix variant when ordering, as the base model may differ in compliance status or lead characteristics compared to the TOM-3046L-R version. Confirm RoHS compliance requirements against the specific datasheet revision. Ensure solder pad dimensions match the target PCB footprint to prevent mechanical stress during assembly.

Selection Notes

Select this component for applications requiring a simple, low-cost analog microphone interface. The -46 dB sensitivity provides adequate gain for many consumer-grade preamplifiers. Consider the 30 Hz lower frequency limit when designing for high-fidelity audio, as it may attenuate deep bass frequencies compared to wider-range alternatives.
