TOM-1545L-R

Overview

The TOM-1545L-R is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features a circular design with omnidirectional polar characteristics. The component operates within a frequency range of 20 Hz to 20 kHz and requires a supply voltage between 2 V and 10 V. Key electrical specifications include a sensitivity of -45 dB ±3 dB and an impedance of 2.2 kOhm. The device utilizes solder pads for surface mounting.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Electret condenser transducer technology
• Analog signal output capability

Applications

• Consumer electronics audio input
• Industrial control systems
• Medical equipment interfaces

Procurement Notes

Verify the specific datasheet version for the TOM-1545L-R to confirm mechanical dimensions and soldering parameters. Ensure compatibility with the required operating voltage range of 2 V to 10 V during circuit design. Cross-reference the sensitivity tolerance of -45 dB ±3 dB against system noise floor requirements.

Selection Notes

Select this component when an omnidirectional response is required for general sound capture. The fixed impedance of 2.2 kOhm must match the preamplifier input stage. Verify that the physical form factor fits the available PCB real estate and that the solder pad termination method aligns with the assembly process.
