AT-4534-TT-R

Overview

The AT-4534-TT-R is a piezoelectric transducer manufactured by PUI Audio, Inc. It features a peak-to-peak voltage rating of 12 V and delivers a sound pressure level of 110 dBA at a resonant frequency of 3.4 kHz. The component has a diameter of 45 mm and a maximum height of 13.70 mm. It utilizes through-hole mounting with PC pin termination types. This device is designed for high-output audio signaling applications requiring robust performance in demanding environments.

Feature Summary

• Externally driven piezoelectric design for high acoustic output
• Compact form factor suitable for space-constrained installations
• Through-hole construction with PC pin terminations for secure board attachment

Applications

• High-decibel audio signaling in industrial equipment
• Security and fire alarm systems requiring clear audible alerts
• Medical devices needing reliable acoustic indicators
• Consumer electronics with high-volume notification requirements

Procurement Notes

Verify the specific datasheet version before procurement to ensure compliance with current RoHS and REACH standards. Confirm that the 12 Vpp drive signal matches your circuit design capabilities. Ensure mechanical clearance allows for the 45 mm diameter and 13.70 mm height dimensions during PCB layout. Check lead times as manufacturing cycles may vary based on production schedules.

Selection Notes

Select this component when high sound pressure levels are critical for user awareness in noisy environments. The 3.4 kHz frequency provides distinct audibility compared to lower-frequency buzzers. Consider the through-hole mounting requirement if surface-mount alternatives are not feasible. Evaluate the 12 V operating voltage against available power rails to determine if additional driver circuitry is necessary for optimal performance.
