Circular cased PCB mounting
High sound output transducers
Requires external drive circuits to operate

These are high-quality internal piezo buzzers produce a crisp and clear sound. They incorporate low power consumption with a broad voltage range and a rich sound, all in a super-compact package.

They can function between 3 V DC to 20 V DC, so they’re compatible with most consumer goods. They operate on a 15 mA supply current to deliver both reliability and energy efficiency. They produce a continuous 95 dB tone that can be clearly heard from a distance, even in noisy conditions.

These piezo buzzer components meet ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards for electrostatic discharge and comply with RoHS (Restriction of Hazardous Substances) guidance. Their small size and loud tone make them a versatile choice that’s suitable for warning devices in industrial workplaces or schools, where there’s high background noise.
