• Consumer appliance alert signals

Procurement Notes

Verify the specific suffix 'BMAQ' against the official Mallory Sonalert datasheet to confirm package dimensions and terminal configuration. Ensure the operating environment temperature range aligns with the component's specified limits before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount piezoelectric solution is required for space-constrained designs. Confirm that the external driver circuit can supply the necessary peak-to-peak voltage and current to achieve the specified acoustic output levels effectively.

Part Context

This part belongs to the Mallory Sonalert AST series of audio products. These devices are designed as transducers requiring external drive circuitry, distinguishing them from self-excited buzzers. They are commonly used in industrial and consumer electronics for audible feedback.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Do not assume cross-compatibility with other manufacturers' parts without verifying electrical parameters and mechanical footprint dimensions.
