AST0927MW-03Q

Overview

The AST0927MW-03Q is a surface-mount magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates at a rated voltage of 3 V with a current consumption ranging from 46 to 90 mA. The device produces an acoustic output of 90 dB measured at 3 V and 10 cm distance, with a resonant frequency of 2.7 kHz. Designed for externally driven applications, it utilizes solder pads for termination and is suitable for compact electronic assemblies requiring audible signaling.

Feature Summary

• Externally driven magnetic transducer design
• Surface mount package configuration
• High acoustic output capability

Applications

• Compact consumer electronics
• Portable medical devices
• Industrial control panels

Procurement Notes

Verify the specific suffix '03Q' against the official Mallory datasheet to confirm exact electrical tolerances and material composition. Ensure the selected variant matches the required operating voltage and mounting footprint specifications for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a low-profile surface-mount solution is required for 3 V systems. The external drive requirement necessitates an accompanying microcontroller or driver circuit within the system design. Evaluate spatial constraints against the 9 mm form factor to ensure adequate clearance for assembly.

Part Context

This part belongs to the Sonalert family of audible warning devices produced by Mallory Sonalert Products Inc. The manufacturer specializes in industrial, medical, and military-grade audio indicators. This specific model represents their surface-mount magnetic technology line, distinct from piezoelectric or internally driven variants.

Replacement Considerations

Consult the official Mallory cross-reference documentation for verified substitutes. Generic equivalents may not match the precise acoustic profile or mechanical dimensions required for strict enclosure fits.
