PUI Audio Piezo Buzzer Transducer, 5mm Length, 78 dBA Sound Level - SMT-0540-T-2-R

This piezo buzzer transducer is a Compact acoustic device designed to provide audible alerts in low-voltage electronic assemblies. It operates as an externally driven sounder suited to surface-mount integration, delivering a clear tone for signalling duties within control panels, instruments and Compact equipment in automation and electrical systems.

Features and Benefits:

• Operates between 2V and 4V supporting low-voltage designs
• Emits 78dBA to ensure discernible alerts in noisy environments
• Frequency range 3500 to 4500Hz for attention-grabbing tones
• Surface-mount format for automated PCB assembly
• Maximum operating temperature 70°C enabling warmer conditions

Applications

• Suitable for alarm signalling in industrial controllers
• Ideal for status indication on handheld test instruments
• Used with access control panels for audible feedback
• Can be used for user alerts in small machinery consoles

What mounting method does it require for PCB assembly?

It fits as an SMD component for placement and reflow soldering on a printed circuit board.

How Compact is the device for tight layouts?

The package measures 5x5mm footprint and a 3mm profile suitable for dense board populations.

What approvals cover hazardous-substance restrictions?

It conforms to both RoHS and REACH substance restriction standards.

How should drive circuitry be specified for reliable tone generation?

Design the driver to supply a stable external drive within the 2 to 4V window and within the stated frequency limits for consistent sound output.
