PUI Audio Piezo Buzzer Transducer, 78dBA Sound Level, Surface Mount Mount - SMT-0540-S-R
This piezo buzzer transducer provides an audible signalling solution for Compact electronic assemblies, converting electrical pulses into a clear sound output for status indication and alerts. It is intended for surface-mount installation on PCBs and operates from a low-voltage supply, making it suitable for integration into control and monitoring modules in industrial and commercial equipment.
Features and Benefits:
• External drive compatibility enables flexible system integration
• 78dBA sound pressure offers recognisable audible alerts
• Operates from 2 to 4V to suit low-voltage circuitry
• Peak acoustic response at 4000 Hz for clear tonal signalling
• Survives operating environments up to 70 °C for reliable duty
• Conforms to REACH and RoHS to meet material regulations
• 78dBA sound pressure offers recognisable audible alerts
• Operates from 2 to 4V to suit low-voltage circuitry
• Peak acoustic response at 4000 Hz for clear tonal signalling
• Survives operating environments up to 70 °C for reliable duty
• Conforms to REACH and RoHS to meet material regulations
Applications
• Suitable for alarm and alert circuits in automation panels
• Ideal for Compact sensor modules requiring audible feedback
• Used with single-board controllers for status indication
• Can be used for test jigs and production-line signalling
• Suitable for handheld instruments needing a small sounder

What mounting approach does it require on a PCB?
It is designed for surface-mount installation to SIT directly on the PCB footprint.
How Compact is the component profile for tight assemblies?
The device presents a very low profile with a height of 2mm to minimise vertical space usage.
What supply voltage range should be provided for correct operation?
Design the driver to deliver between 2V and 4V to achieve rated performance.
What acoustic level can I expect for warning applications?
The transducer produces approximately 78 dBA, suitable for audible alerts in enclosed equipment.
Which environmental limit is critical for thermal design?
The maximum continuous operating temperature is 70 °C, so thermal planning should ensure local temperatures remain below this value.
