TOM-1145S-C33-R

Overview

The TOM-1145S-C33-R is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern and operates within a voltage range of 2 V to 10 V. The sensitivity is specified as -45 dB with a tolerance of ±3 dB. The component has a diameter of 4 mm (0.157 inches) and utilizes a solderless bullseye mounting style. It is RoHS compliant and lead-free.

Feature Summary

• Omnidirectional acoustic response for uniform sound capture from all directions
• Electret condenser technology providing analog audio signal output
• Solderless bullseye mounting interface for simplified assembly

Applications

• General purpose audio recording devices
• Consumer electronics requiring compact microphone solutions
• Voice recognition systems

Procurement Notes

Verify the specific datasheet version for the TOM-1145S-C33-R to confirm current electrical tolerances and mechanical dimensions. Ensure compatibility with the target circuit's biasing requirements, specifically the 2 V to 10 V operating range. Confirm that the solderless bullseye termination method aligns with the printed circuit board design constraints.

Selection Notes

Select this component when an omnidirectional pickup pattern is required for broad sound field coverage. The 4 mm diameter makes it suitable for space-constrained enclosures. Verify that the application environment supports the operational voltage limits and that the analog output format matches the downstream processing input specifications.

Part Context

This part belongs to the PUI Audio TOM series of electret condenser microphones. These components are designed for general-purpose audio applications where size and cost efficiency are prioritized. The series typically offers various sensitivity levels and mounting options to accommodate different enclosure designs and acoustic requirements.

Replacement Considerations

Cross-reference with other PUI Audio models in the TOM series for alternative sensitivity or package configurations. Ensure any substitute maintains the same 4 mm diameter and omnidirectional characteristic to fit existing mechanical footprints without modification.
