PUI Audio Piezo Buzzer Transducer, 13.8mm Diameter, 80dBA Sound Level - AT-1438-TWT-R


This piezo buzzer transducer is an audible signalling device designed for external-drive applications in industrial and electronic systems. It produces a clear tone for alerting and status indication, operating across a wide temperature range and featuring through-hole mounting for secure board integration.

Features and Benefits:


• 4100Hz maximum frequency delivers distinct audible alerts
• 80dBA sound level ensures perceptible notifications in noisy environments
• 1 to 20V external drive supports flexible supply arrangements
• 1mA supply current minimises power draw for low-energy designs
• 13000pF capacitance provides predictable resonance for tone stability
• Tin plated red copper termination facilitates reliable solder connections

Applications


• Suitable for control panels requiring audible fault signalling
• Ideal for industrial automation alert and status indicators
• Used for instrumentation alarms in harsh-temperature environments
• Can be used with test rigs requiring low-current audible prompts

What mounting method does it require for PCB assembly?


It uses a through-hole mount style that secures the component mechanically and electrically during wave or hand soldering.

Which environmental temperatures are acceptable for operation?


It functions between -40°C and +70°C without degradation of electrical characteristics.

What termination materials are provided for solderability?


Termination is MADE from tin plated red copper to provide good wetting and joint formation.

How does capacitance affect use with external drive circuits?


The 13000pF capacitance influences the resonant behaviour and must be considered when matching drive impedance and frequency for consistent tone output.
