PUI Audio 80 dBA Through Hole External 11.3 mm Piezo Buzzer Transducer 13.8 mm 1 V Min 20V Max

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.

• 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

• 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

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

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

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

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