Overview
The AST0932ME-05TRQ is a magnetostrictive buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC input with a rated voltage of 5V and a range of 4 to 7V. The device generates an acoustic signal at a frequency of 3.2kHz. Its physical dimensions are 8.7mm x 8.7mm, designed for surface-mount technology (SMD) installation.
Feature Summary
- Utilizes magnetostrictive technology for sound generation
- Designed for surface-mount panel integration
- Operates on low-voltage direct current supply
Applications
- Electronic equipment status indication
- Low-voltage alarm systems
- Compact consumer electronics audio signaling
Procurement Notes
Verify the specific suffix TRQ against official Mallory Sonalert documentation to confirm tape-and-reel packaging requirements. Ensure the input circuitry strictly adheres to the 4V to 7V operating range to prevent component damage. Confirm that the PCB footprint matches the 8.7mm x 8.7mm SMD outline drawing provided in the manufacturer's sales specifications.
Selection Notes
Select this component when a compact, surface-mount solution is required for audible signaling in space-constrained designs. The magnetostrictive technology offers distinct acoustic characteristics compared to piezoelectric alternatives. Ensure the application environment supports the specified voltage range and that the mounting process accommodates the small form factor without mechanical stress.
Part Context
This part belongs to the AST series of buzzers from Mallory Sonalert Products Inc., which focuses on miniature audio components. The series includes various models with different voltages and mounting styles. The AST0932ME-05TRQ specifically addresses the need for small-footprint, low-voltage audible alerts in modern electronic assemblies.
Replacement Considerations
Consult official Mallory Sonalert cross-reference guides for verified substitutes. Generic magnetostrictive buzzers may not match the precise acoustic output or electrical characteristics. Verify dimensional compatibility before substituting with other SMD buzzer models.
