AST0827MW-03AQ

Overview

The AST0827MW-03AQ 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 of 80 mA. The device produces an acoustic output of 85 dB at 10 cm and functions at a frequency of 2.731 kHz. It features an externally driven transducer design and utilizes SMD packaging.

Feature Summary

• Externally driven magnetic transducer technology
• Surface-mount device (SMD) package configuration
• High acoustic output level relative to power consumption

Applications

• Electronic equipment status indication
• Portable device audio signaling
• Industrial control panel alerts

Procurement Notes

Verify the specific suffix 'AQ' against the manufacturer's official datasheet to confirm RoHS compliance and lead time specifications. Ensure the ordering part number matches the exact electrical parameters required for the target circuit design before finalizing procurement.

Selection Notes

Select this component when a low-profile, surface-mount magnetic buzzer is required for space-constrained designs. The external drive requirement necessitates an accompanying driver circuit within the system architecture. Confirm that the 3 V operating voltage aligns with the available supply rails in the application.

Part Context

This component belongs to the Mallory Sonalert magnetic buzzer family, designed for compact electronic assemblies. It serves as an alternative to through-hole or piezoelectric variants where specific acoustic characteristics and mounting constraints dictate the use of a surface-mount magnetic solution.

Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitute part numbers. Direct replacements must match the 3 V rating, SMD footprint, and acoustic performance specifications to ensure functional equivalence.
