AST0827MW-03BQ

Overview

The AST0827MW-03BQ is a surface-mount magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a 3V DC supply with a rated current of 100mA. The device produces an 80dB sound pressure level at 3V measured at 10cm distance and functions at a frequency of 2.7kHz. Its compact dimensions are 8.5mm x 8.5mm with a maximum height of 3.4mm. The component utilizes external driving circuitry and features solder pad termination for PCB integration.

Feature Summary

Surface-mount magnetic transducer technology
External driver requirement for operation
Compact low-profile form factor

Applications

Embedded electronic devices
Portable consumer electronics
Industrial control panels

Procurement Notes

Verify the specific suffix 'BQ' against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the design supports external drive circuits as this unit lacks internal oscillators. Confirm RoHS compliance status through the latest certified documentation provided by Mallory Sonalert Products Inc.

Selection Notes

Select this component when space constraints require a small footprint buzzer. The 3V rating suits battery-powered applications. Verify that the host circuit can provide the required 100mA peak current. Consider the 2.7kHz tone for audible alerts in moderate noise environments.

Part Context

This part belongs to the AST series of micro buzzers from Mallory Sonalert. The series focuses on miniaturized audio solutions for modern electronics. The magnetic construction offers distinct acoustic characteristics compared to piezoelectric alternatives in similar size classes.

Replacement Considerations

Check for direct substitutes within the AST series such as AST0827MW variants. Verify pin compatibility and acoustic output levels before substituting with other manufacturers' surface-mount buzzers.
