AST200Q

Overview

The AST200Q is a board-mount piezoelectric buzzer from the Mallory Sonalert XDUCR series. It operates on a 2-4V peak-to-peak AC input and produces a continuous tone at 2731Hz with an 85dB sound pressure level. The unit measures 9x9x4mm and is supplied in tube packaging.

Feature Summary

• Piezoelectric transducer technology for reliable audio indication
• Compact surface-mount form factor suitable for dense circuit boards
• Continuous tone output optimized for clear status signaling

Applications

• Medical device alarm systems
• Industrial control panel indicators
• Consumer electronics status alerts

Procurement Notes

Verify the specific voltage tolerance and frequency deviation against the official datasheet before integration. Confirm that the 2-4Vpp drive signal matches the design requirements to ensure optimal acoustic performance without damaging the piezoelectric element.

Selection Notes

Select this component when a low-profile, board-mount solution is required for high-frequency audible alerts. The XDUCR series offers a balance of size and acoustic output for applications where space is limited but clear indication is critical.
