Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage and acoustic specifications. Confirm that the through-hole package dimensions match the target printed circuit board layout. Ensure the operating frequency aligns with the intended application's detection requirements before finalizing procurement decisions.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact 8.7mm square buzzer is required for through-hole assembly. The 3V operating voltage makes it suitable for low-voltage digital logic circuits. Consider the 85dB output level for environments where moderate volume is sufficient for user notification without excessive noise pollution.

Alarms, Buzzers, And Sirens Part Context

This part belongs to East Electronics' series of piezoelectric buzzers designed for general-purpose audio signaling. The SFM series typically offers various form factors and acoustic outputs to meet diverse industrial and consumer electronics needs. This specific model provides a balance of size and sound pressure for standard applications.

Alarms, Buzzers, And Sirens Replacement Considerations

The SFM-5540-03A is a related product from the same manufacturer but differs in physical dimensions (5x5mm) and electrical characteristics (3.6V, 4000Hz). Verify mechanical fit and electrical compatibility before substituting.
