AST1440MATRQ

Overview

The AST1440MATRQ is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. This component operates at a frequency of 1440 Hz and features an active driver circuit, allowing it to produce sound when supplied with a DC voltage. The device is designed for surface mount technology (SMT) applications, utilizing a compact form factor suitable for space-constrained electronic assemblies. It typically requires a supply voltage within the range of 3V to 5V DC to function correctly, generating an acoustic output level specified in decibels at a standard distance. The unit is housed in a plastic case with integrated terminals for electrical connection.

Feature Summary

• Active piezoelectric design eliminates the need for external oscillator circuits
• Surface mount construction facilitates automated assembly processes
• Integrated driver circuitry ensures straightforward DC voltage operation

Applications

• Consumer electronics audio signaling
• Industrial control panel alerts
• Medical device status indicators

Procurement Notes

Verify the specific suffix codes on the ordering information to confirm the exact acoustic output level and terminal configuration required for your design. Ensure that the PCB footprint matches the mechanical dimensions provided in the official datasheet. Confirm the operating voltage range aligns with your system's power supply rails before finalizing procurement decisions.

Selection Notes

Choose this component when an active buzzer with SMT compatibility is required. Consider the acoustic requirements and physical size constraints of the enclosure. Verify that the drive voltage matches available system voltages. Evaluate the mounting orientation and accessibility of the sound output port during the mechanical design phase.

Part Context

This part belongs to the AST series of piezoelectric buzzers from Mallory Sonalert. The series offers various frequencies and package types to meet diverse audio signaling needs.
