AST100TRQ

Overview

The AST100TRQ is a surface-mount piezoelectric buzzer from Mallory Sonalert, designed for board-level integration. It operates at a rated voltage of 5 V and produces a sound at a frequency of 4 kHz. The component utilizes SMT technology with a compact form factor measuring 18 x 5 mm. It is supplied in a reel format for automated assembly processes.

Feature Summary

• Surface mount technology (SMT) design for automated PCB assembly
• Piezoelectric transducer mechanism for audio indication
• Compact 18 x 5 mm footprint suitable for space-constrained applications

Applications

• Electronic device status indication
• Control panel audio alerts
• Consumer electronics signaling

Procurement Notes

Verify the specific suffix TRQ confirms reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure operating temperature range of -20°C to 70°C meets environmental requirements. Validate active product status before procurement planning.

Selection Notes

Select this model for low-voltage 5 V systems requiring surface-mount integration. Consider the 4 kHz frequency for audible alert clarity. Evaluate the 18 x 5 mm dimensions against PCB layout constraints. Compare against through-hole alternatives if reflow soldering capabilities are unavailable.

Part Context

This component belongs to the Mallory Sonalert buzzer portfolio, specializing in piezoelectric audio indicators. The manufacturer provides industrial-grade sound solutions with various mounting options. The AST series focuses on compact, high-performance acoustic devices for modern electronic assemblies.

Replacement Considerations

No public substitute part numbers are documented. Cross-reference with other Mallory Sonalert SMT buzzers for similar voltage and frequency specifications if availability is an issue.
