Utilizes magnetic transducer technology for acoustic output
Supports low-voltage DC operation suitable for battery-powered systems

Alarms, Buzzers, And Sirens Applications

Low-power electronic indicators
Battery-operated alarm systems
Portable medical device alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating requirements against the 1.5 Vp-p specification before integration. Confirm that the 15 mA maximum current draw aligns with the available power supply capacity in the target application. Ensure mechanical compatibility with the through-hole PC pin termination style during PCB layout design.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, low-voltage magnetic buzzer is required. The 2048 Hz frequency provides a distinct audible tone. Consider the 1.25 V to 2.5 Vp-p operating range for compatibility with standard logic levels or small battery cells. Verify that the top port location meets the acoustic directionality needs of the enclosure.
