AT-1425-TWT-3-R

Overview

The AT-1425-TWT-3-R is an externally driven magnetic buzzer manufactured by PUI Audio, Inc. This component operates at a rated voltage of 1.5 V with a current rating of 30 mA. It produces a sound pressure level of 85 dB measured at 10 cm distance and 1.5 V input. The device features a self-resonant frequency of 2.5 kHz and utilizes through-hole mounting for PCB integration. Its physical dimensions are 22.5 mm in length, 17 mm in width, and 14 mm in height. The unit is RoHS compliant and designed for industrial automation applications.

Feature Summary

Externally driven electromagnetic transducer design
Through-hole PCB mounting configuration
RoHS compliant construction

Applications

Industrial automation systems
Commercial alarm devices
Electronic indicators

Procurement Notes

Verify the specific datasheet version to confirm compliance details and mechanical tolerances before integration. Ensure that the driving circuit provides the required peak-to-peak signal characteristics suitable for this externally driven magnetic transducer. Confirm that the operating environment remains within the specified electrical limits to maintain performance reliability.

Selection Notes

Select this component when a low-voltage, high-sensitivity magnetic buzzer is required for through-hole assembly. Consider the 2.5 kHz resonant frequency for audible alert applications. Evaluate the 85 dB output level against acoustic requirements. Verify compatibility with 1.5 V supply rails and 30 mA current consumption constraints in the target design.
