AI-1440-TWT-12V-R

Overview

The AI-1440-TWT-12V-R is a piezoelectric buzzer manufactured by PUI Audio, designed for board-mount applications. It operates at a rated voltage of 12 VDC with a current rating of 7 mA. The device produces a continuous tone at a frequency of 4 kHz and achieves a sound pressure level of 80 dBA. It features through-hole solder pin termination and has a circular form factor with a diameter of 13.8 mm and a height of 7.5 mm.

Feature Summary

• Piezoelectric transduction mechanism for reliable acoustic signaling
• Continuous tone generation capability for steady-state alerts
• Through-hole mounting style for secure PCB integration

Applications

• Electronic equipment status indicators
• Appliance operational alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure that the 12 VDC operating voltage aligns with the target circuit design to prevent component damage or performance degradation.

Selection Notes

Select this component when a compact, low-power audible indicator is required for 12 VDC systems. The 80 dBA output provides clear audibility in moderate noise environments. Consider the 13.8 mm diameter and 7.5 mm height for mechanical clearance constraints on the printed circuit board layout.

Part Context

This component belongs to the AI series of audio indicators from PUI Audio. It is categorized as a piezoelectric buzzer intended for general-purpose electronic signaling. The product line focuses on providing cost-effective and reliable acoustic solutions for various consumer and industrial electronics applications.
