Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific drive circuit requirements before procurement, as this is a passive component requiring external excitation. Confirm that the 1.5 VDC rating aligns with your system's power supply. Ensure the PCB layout accommodates the 12 mm diameter and 8.7 mm height constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Alarms, Buzzers, And Sirens Selection Notes

Select this part when a low-profile, through-hole magnetic buzzer is needed for 1.5 VDC applications. It is suitable for designs where external driving circuits are already present or planned. Consider the 40 mA current consumption for power budget calculations. Ensure the operating environment stays within the specified -20°C to +60°C temperature range.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Mallory Sonalert buzzer family, specifically designed for industrial and commercial audio indication. As a passive magnetic type, it differs from active piezoelectric buzzers by requiring an external oscillator signal. The 12 mm size makes it suitable for space-constrained PCB layouts where reliable acoustic output is necessary.
