PUI Audio 95 dBA Surface External Piezo Buzzer Transducer 3.2 mm 3 V Min 8.5 mm 8.5mm 5V Max

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.

• 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

• 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

It needs an external drive signal rather than an internal oscillator so tone generation is controlled by the host circuit.

With a low-profile height it permits slim enclosures while still providing distinct audio output.

It is provided as a surface-mount device to accommodate reflow soldering and automated placement.

The device is rated to operate up to 85 °C, defining its usable thermal boundary for system design.
