PUI Audio Piezo Buzzer Transducer, 95dBA Sound Level, 3V to 5V Supply Voltage - SMT-0931-S-R
This piezo buzzer transducer provides an audible alerting function for electronic systems, operating from a low-voltage external drive. It is a compact, surface-mounted sound source designed for integration into consumer and industrial electronic assemblies where a clear audible signal is required without adding significant height.
Features and Benefits:
• Operates from 3V to 5V for flexible supply options
• Produces 95 dBA sound output for strong audible indication
• Frequency range 3100 to 3600 Hz for distinct tone signalling
• Surface-mount form for automated PCB assembly
• Maximum operating temperature 85 °C for moderate thermal environments
• Conforms to RoHS and REACH regulations for material compliance
• Produces 95 dBA sound output for strong audible indication
• Frequency range 3100 to 3600 Hz for distinct tone signalling
• Surface-mount form for automated PCB assembly
• Maximum operating temperature 85 °C for moderate thermal environments
• Conforms to RoHS and REACH regulations for material compliance
Applications
• Suitable for alarms and notifications in consumer electronics
• Ideal for status indicators in automation panels
• Used with control circuits in electrical equipment
• Can be used for audible alerts in mechanical systems

What drive arrangement does it require for activation?
It needs an external drive signal rather than an internal oscillator so tone generation is controlled by the host circuit.
How does its profile affect enclosure design?
With a low-profile height it permits slim enclosures while still providing distinct audio output.
What mounting method is used for PCB assembly?
It is provided as a surface-mount device to accommodate reflow soldering and automated placement.
What environmental temperature limits apply during operation?
The device is rated to operate up to 85 °C, defining its usable thermal boundary for system design.
