Description

This Small Piezoelectric Buzzer – 5V Active Buzzer is a compact and efficient electronic component designed to emit a sound when voltage is applied. Being an active buzzer, it has an internal oscillating source, meaning it requires just a power supply to operate—no need for additional circuitry to produce sound.

It is often used in DIY electronics, alarms, notifications, and embedded systems. The 2RA variant has a small, round form factor with two pins for easy through-hole mounting.
