AT-1720-TT-R

Overview

The AT-1720-TT-R is an externally driven piezoelectric transducer manufactured by PUI Audio, Inc. It operates with a resonant frequency of 2 kHz and delivers a sound pressure level of 70 dBA at 3 V measured at 10 cm. The device accepts a maximum supply voltage of 25 VAC and draws a maximum operating current of 3 mA. Designed for through-hole mounting, it features PC pins for soldering and has a compact diameter of 17 mm.

Feature Summary

Externally driven piezoelectric design for flexible signal integration
Compact 17 mm diameter form factor suitable for space-constrained assemblies
Through-hole construction with PC pin termination for reliable board attachment

Applications

Audio indicators in consumer electronics
Status alerts in industrial control panels
Audible feedback mechanisms in medical devices

Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet prior to implementation. Confirm that the through-hole footprint matches your PCB layout requirements. Ensure the driving circuit can provide the necessary voltage and current specifications without exceeding the maximum ratings defined in the component documentation.

Selection Notes

Select this component when a low-profile, high-efficiency acoustic indicator is required for through-hole assembly. The 2 kHz resonant frequency provides clear audibility for status notifications. Consider the 70 dBA output level relative to the ambient noise environment of the target application to ensure adequate signal detection.
