PUI Audio Piezo Buzzer Transducer, 93dBA Sound Level, 3.5mm Height - SMT-1028-S-2-R

This piezo buzzer transducer converts electrical drive signals into audible alerts for electronic assemblies. Designed for surface-mount integration, it operates from low-voltage external drive and produces a clear acoustic output suited to Compact assemblies and panel-mounted alert systems.

Features and Benefits:

• Operates at 3 to 4.5V for low-voltage system compatibility
• Produces 93dBA SPL for high audibility in noisy environments
• Frequency range 2600 to 3600Hz for attention-grabbing tones
• Surface-mount package enables automated PCB assembly
• Withstands temperature 85°C for elevated ambient conditions

Applications

• Suitable for audible alarms in industrial controllers
• Ideal for indicators in automation panels
• Used with Compact sensor modules requiring alerts
• Can be used for warning tones in handheld instruments

What mounting approach does it require for PCB assembly?

It uses a surface-mount configuration that supports pick-and-place and reflow soldering for efficient production workflows.

What acoustic performance can I expect at typical operating voltages?

When driven within the specified 3 to 4.5V range, it delivers a sound pressure level of 93dBA at its rated conditions, providing a high-SPL alert.

How tolerant is it to elevated operating environments?

The device is rated to function up to 85°C, allowing operation in warm industrial compartments without premature thermal degradation.

Which drive method should be used to excite the element?

It requires an external drive circuit rather than an internal oscillator, enabling user control over tone and modulation.
