AT-2235-TT-R

Overview

The AT-2235-TT-R is a piezoelectric transducer manufactured by PUI Audio, Inc. It operates at a resonant frequency of 3.5 kHz and requires an externally driven circuit. The component is rated for a voltage range of 1 to 30 V with a supply current of 3 mA. It produces a sound pressure level of 75 dBA measured at 3 V from a distance of 10 cm. Designed for through-hole mounting via PC pins, the unit features a top port location and functions within an operating temperature range of -40°C to 90°C.

Feature Summary

Externally driven piezoelectric technology for signal generation
Through-hole mounting configuration using PC pins
Top port acoustic output design

Applications

Audio indicators and alert systems
Buzzer applications requiring external drive signals
Industrial control panel feedback

Procurement Notes

Verify the specific electrical requirements against your design, as this component is externally driven and not self-oscillating. Confirm that the 1–30 V input range aligns with your driver circuit capabilities. Ensure the through-hole footprint matches your PCB layout constraints. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this model when a high-frequency piezo element is needed for audible alerts. It suits designs where the driving circuitry is separate from the transducer. Consider the 75 dBA output level for volume requirements. The wide voltage tolerance allows flexibility in power supply design. Verify thermal limits if the application involves extreme ambient temperatures.
