AT-1442-TT-WP-R

Overview

The AT-1442-TT-WP-R is an externally driven piezo transducer manufactured by PUI Audio, Inc. It operates within a voltage range of 3 to 20 VAC and draws a current of 12 mA. The device produces a sound pressure level of 84 dBA at 10 V measured from a distance of 10 cm. Its resonant frequency is 4.25 kHz. The component utilizes through-hole mounting with PC pins for secure integration into circuit boards.

Feature Summary

• Externally driven piezoelectric design
• Through-hole PC pin termination
• Omnidirectional acoustic output

Applications

• Audible alarms and warning systems
• Industrial control panel indicators
• Consumer electronics status alerts

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct electrical characteristics and mechanical configuration. Confirm that the through-hole footprint matches the target PCB layout. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when an audible alert is required without internal oscillator circuits. Ensure the driving circuit can supply the necessary peak current for the piezo element. Verify that the operating voltage remains within the specified 3 to 20 VAC range to prevent damage or insufficient output.

Part Context

This part belongs to PUI Audio's line of externally driven piezo transducers. These components are designed for applications requiring simple drive signals to generate sound. They differ from self-excited buzzers by lacking internal oscillators, allowing for variable frequency operation.

Replacement Considerations

Consult official substitution guides for compatible piezo transducers with matching 4.25 kHz resonance and 84 dBA sensitivity. Verify mechanical dimensions and pin compatibility before replacing.
