Procurement Notes
Verify the specific suffix configuration against the official Mallory Sonalert datasheet to ensure compatibility with required acoustic output and electrical characteristics. Confirm that the 9-12 VDC operating range aligns with the target system power supply. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the PCB footprint matches the 44.45 mm diameter and 15 mm height constraints.
Selection Notes
Select this component when a high-intensity audible alert is required within a compact circular footprint. The internal driver simplifies circuit design by eliminating external oscillators. Consider the 630 mA current draw for power budget calculations. The wide frequency range allows for distinct tone selection depending on the driving signal. Verify thermal management capabilities given the specified operating temperature limits.
