AT-1740-TT-R

Overview

The AT-1740-TT-R is a piezoelectric transducer manufactured by PUI Audio, Inc. It operates at a resonant frequency of 4 kHz and delivers a sound pressure level of 78 dBA. The device is rated for a voltage of 5 VAC and draws an operating current of approximately 3 mA. Designed for through-hole mounting, it features solder pin termination. The physical dimensions are compact, suitable for space-constrained electronic assemblies requiring audible signaling.

Feature Summary

Piezoelectric construction for reliable acoustic output
Through-hole mounting configuration with solder pins
Single-tone operation mode

Applications

Appliance status indicators
Industrial control panel alerts
Consumer electronics audio signaling

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical footprint details before integration. Ensure that the driving circuit provides the required 5 VAC signal amplitude to achieve the specified 78 dBA output level. Confirm compliance with relevant environmental regulations such as RoHS requirements applicable to your region.

Selection Notes

Select this component when a simple, cost-effective audible alert is needed without complex tone generation circuits. Its single-tone nature makes it ideal for basic on/off status indication. Consider the 4 kHz resonance for optimal efficiency in air-coupled applications where high-frequency clarity is prioritized over low-frequency bass response.

Part Context

This part belongs to PUI Audio's standard line of piezoelectric transducers, widely used in industrial and consumer sectors. The company specializes in audio components including speakers, sirens, and microphones, leveraging decades of experience in sound solution design for diverse market applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should verify mechanical compatibility and electrical specifications against alternative suppliers if sourcing constraints arise.
