AST0927MW-05TRQ

Overview

The AST0927MW-05TRQ is a piezoelectric buzzer from the AST series by Mallory Sonalert Products Inc. It features surface mount (SMD/SMT) termination and operates on a 5V DC input. The device provides an internal driver for alarm functions with a continuous tone output at 2.9 kHz. It delivers a sound pressure level of 85 dB at 10 cm and draws 40 mA of current. The unit measures 9.2 mm x 9.2 mm x 3.6 mm and supports a voltage range of 4.5 to 5.5 V.

Feature Summary

Piezoelectric technology with integrated internal driver circuitry
Surface mount design for automated PCB assembly
Continuous tone operation mode

Applications

Industrial control panel indicators
Medical equipment audio alerts
Consumer electronics status signaling

Procurement Notes

Verify that the suffix TRQ corresponds to the tape and reel packaging format as indicated in distributor listings. Confirm the specific voltage rating and acoustic performance against the official Mallory Sonalert datasheet prior to integration. Ensure compatibility with standard SMD reflow soldering profiles for the specified package dimensions.

Selection Notes

Select this component for applications requiring compact surface mount audio indication. The 5V operating voltage suits low-power digital logic interfaces. Consider the 85 dB acoustic output for environments requiring moderate audible alerting without excessive power consumption.

Part Context

This part belongs to the AST series of piezoelectric buzzers designed for board-level mounting. It complements through-hole and panel-mount options by offering a low-profile solution suitable for dense PCB layouts. The series emphasizes reliability in industrial and medical audio indicator roles.
