Procurement Notes

Verify the specific suffix designation against official Mallory Sonalert documentation to confirm exact acoustic and electrical characteristics. Ensure compatibility with automated surface-mount assembly processes. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before integration into regulated products.

Selection Notes

Select this component for designs requiring SMT mounting and low-voltage DC operation. Compare performance metrics against piezoelectric alternatives if higher sound pressure levels are required. Evaluate thermal management requirements given the specified operating temperature limits and ensure the PCB layout supports the side-port acoustic output direction.

Part Context

This component belongs to the AST series of surface-mount transducers from Mallory Sonalert. The series focuses on compact audio indicators suitable for modern electronics manufacturing.
