TOM-1545S-C33

Overview

The TOM-1545S-C33 is an omnidirectional electret microphone manufactured by PUI Audio. It features a 4 mm diameter housing with solder pin termination for through-hole mounting. The device operates at a voltage of 2 V and presents an impedance of 2.2 kOhms. Its sensitivity is rated at -44 dB, allowing for effective audio capture in compact electronic assemblies.

Feature Summary

• Omnidirectional acoustic design for uniform sound pickup
• Compact 4 mm cylindrical form factor suitable for space-constrained applications
• Through-hole solder pin termination for secure board integration

Applications

• Consumer electronics audio input modules
• Portable communication devices
• Industrial control panel voice interfaces

Procurement Notes

Verify the specific suffix C33 against the manufacturer datasheet to confirm terminal configuration and tolerance specifications. Ensure the operating voltage aligns with the 2 V requirement before integration into the circuit design.

Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for through-hole assembly. Compare sensitivity and impedance requirements against alternative models like the TOM-1545P-R if surface mount technology is preferred instead.

Part Context

This part belongs to the TOM series of microphones from PUI Audio. It shares similar acoustic characteristics with other models in the line but differs in physical dimensions and termination style, specifically utilizing pins rather than pads or leads.

Replacement Considerations

TOM-1545P-R offers identical acoustic performance with surface mount termination. POM-2242P-C33 provides a larger 6 mm diameter option with comparable electrical specifications.
