Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version to confirm thermal handling capabilities, particularly regarding manual soldering temperatures up to 350°C for five seconds. Ensure the passive nature of the component aligns with the driving circuit design, as it requires an external oscillator signal rather than operating on DC voltage alone. Cross-reference dimensions against PCB layout constraints.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, passive buzzer is required for space-constrained designs. The 3V nominal voltage suits battery-powered or low-voltage logic circuits. Consider the 17 Ohm impedance for driver compatibility. The passive type necessitates an external square wave input, distinguishing it from active buzzers that generate sound internally.

Alarms, Buzzers, And Sirens Part Context

This part belongs to Seltech's line of surface-mount alarms and buzzers. It is categorized under passive magnetic buzzers, differing from active variants by its reliance on external drive signals. The 4x4 mm size places it in the micro-buzzer category, intended for integration into small consumer electronics or industrial control panels where minimal board space is available.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 4x4 mm footprint, 2.00 mm height, 3V nominal voltage, and 4000 Hz resonant frequency. Verify impedance compatibility (approx. 17 Ohms) and passive operation requirements. Check for identical mounting pad configurations to ensure PCB reuse without redesign.
