AT-2720-TT-R

Overview

The AT-2720-TT-R is a piezoelectric transducer manufactured by PUI Audio, Inc. It operates with a maximum supply voltage of 30VAC and draws a maximum operating current of 3.5mA. The device features a self-resonant frequency of 2.048 kHz and produces a sound pressure level of 88 dBA at a distance of 100mm. Physical dimensions are approximately 26.5mm x 23mm with a height of 9mm. It utilizes through-hole solder pin termination for mounting.

Feature Summary

Externally driven buzzer module designed for precise tone generation
Piezoelectric construction for reliable audio indication
Through-hole mounting style for secure PCB integration

Applications

Appliance status indicators
Industrial control panel alerts
Security system signaling

Procurement Notes

Verify the specific datasheet version to confirm mechanical tolerances and electrical ratings before finalizing designs. Ensure the driving circuit can provide the necessary voltage and current without exceeding the 30VAC and 3.5mA limits. Confirm that the through-hole footprint matches the target PCB layout. Check for RoHS compliance requirements if applicable to the end product regulations.

Selection Notes

Select this component when a compact, externally driven piezo transducer is required for audible alerts. The 2.048 kHz resonant frequency provides a distinct tone suitable for user feedback. Consider the 88 dBA output level relative to the ambient noise environment of the application. The through-hole package offers robust mechanical stability compared to surface-mount alternatives in high-vibration settings.
