AST605TRQ

Overview

The AST605TRQ is a surface-mount piezoelectric buzzer manufactured by Mallory Sonalert. It operates at a fixed frequency of 2.4 kHz and features a compact form factor with dimensions of 12.6 mm x 12.6 mm x 7 mm. Designed for automated assembly, this component is supplied in tape-and-reel packaging to facilitate efficient SMT production processes.

Feature Summary

• Surface-mount technology construction for automated PCB assembly
• Piezoelectric transducer mechanism for audible signaling
• Compact rectangular footprint suitable for space-constrained designs

Applications

• Industrial control panel indicators
• Consumer electronics status alerts
• Automotive interior warning systems

Procurement Notes

Verify the specific reel quantity and tape specifications against the manufacturer's latest shipping documentation before ordering. Confirm that the surface-mount pad layout matches your PCB design requirements. Ensure storage conditions comply with moisture sensitivity level guidelines to maintain component reliability during soldering.

Selection Notes

Select this model when a low-profile, surface-mount solution is required for high-frequency audible alerts. The 2.4 kHz tone provides distinct audibility compared to lower-frequency alternatives. Consider the 12.6x12.6 mm footprint constraints during mechanical design integration.

Part Context

This component belongs to the Mallory Sonalert line of audio indicators. It represents the transition from through-hole to surface-mount technologies in industrial signaling devices. The TRQ suffix typically denotes the tape-and-reel packaging format used for high-volume manufacturing environments.

Replacement Considerations

Direct replacements must match the 12.6x12.6x7 mm package and 2.4 kHz frequency. Verify voltage compatibility and mounting hole alignment if substituting with other SMT buzzers.
