Procurement Notes
Verify the specific datasheet version provided by the manufacturer or authorized distributor to confirm exact electrical tolerances and mechanical drawings. Ensure that the operating voltage does not exceed the maximum rating of 20 V to prevent component damage. Confirm that the mounting method aligns with the through-hole PC pin specification during PCB layout design.
Selection Notes
Select this component when a compact, externally driven piezo buzzer is required for audible signaling. The 3.6 kHz resonant frequency provides distinct audio output suitable for alert applications. Consider the 80 dBA sound pressure level relative to the ambient noise environment of the target application to ensure adequate audibility.
