Active Piezo Buzzer 3V To 12V

The Active Piezo Buzzer (3V–12V) is a compact and reliable sound device that produces a loud, clear tone when powered. Unlike passive buzzers, this active version has a built-in oscillator circuit, so it only needs a direct DC supply to generate sound—no external driver is required. It works across a wide voltage range from 3V to 12V, making it highly versatile.

Commonly used in alarm circuits, timers, microcontroller projects, security systems, and electronic toys, this buzzer ensures consistent performance with minimal power consumption. Its lightweight design and PCB-mount package make it easy to integrate into both professional and DIY electronics.

With a simple two-pin connection, this buzzer is user-friendly and efficient. Whether you are building Arduino projects, sensor alarms, or industrial indicators, this component guarantees dependable operation and a clear audible alert.
