AT-2429-TWT-R

Overview

The AT-2429-TWT-R is a piezoelectric transducer manufactured by PUI Audio, designed for PCB mounting applications. It operates with a peak-to-peak voltage of 12V and draws a current of 8mA. The device features a self-resonant frequency of 2.9 kHz and produces a sound pressure level of 90 dBA. Its physical dimensions include a diameter of 23.8 mm and a depth of 16 mm. The component supports an operating temperature range from -40°C to +85°C and utilizes solder pin termination.

Feature Summary

Piezoelectric transduction mechanism for audio signal generation
Through-hole solder pin termination for printed circuit board integration
Wide operational temperature tolerance suitable for diverse environments

Applications

Electronic equipment status indicators
General purpose audio alerts
Control panel signaling systems

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation before finalizing design specifications. Confirm that the 12Vpp drive requirement aligns with the target circuit capabilities. Ensure the through-hole footprint matches the intended PCB layout constraints. Cross-reference the RoHS and REACH compliance details provided in the latest technical release to meet regulatory standards.

Selection Notes

Select this component when a high-output piezoelectric indicator is required within a compact cylindrical form factor. The 2.9 kHz resonance provides distinct audibility for alert purposes. Consider the 12Vpp drive requirement during driver circuit design to ensure adequate acoustic output without exceeding current limits. Evaluate the -40°C to +85°C range against environmental conditions.
