5V DC Active Magnetic Piezo Buzzer
The 12mm 5V DC Active Magnetic Piezo Buzzer is an industry-standard acoustic indicator engineered for direct insertion into printed circuit boards (PCBs) and breadboard layouts. Classified under the popular TMB12A05 form factor, this standalone electronic component features an integrated internal oscillation circuit that generates a loud, fixed frequency 2.3kHz continuous tone without requiring any external PWM wave manipulation—simply apply 5V across its pins for instant audio alerts. Built with a rugged, black PBT housing and protective top sealing tape, it operates with a tiny current footprint under 30mA. This efficient design makes it highly favored by electronic product developers for integrating audible warning systems, fault condition beepers, POS terminal chimes, microwave cooker alerts, and custom DIY micro-controller circuits powered by Arduino, PIC, or ESP32 boards.

The 5V Active Buzzer Module (12mm) is a compact sound-generating device designed for simple audio alert applications. Unlike passive buzzers, this active buzzer has a built-in oscillator, allowing it to produce sound directly when powered—no external signal generation required. It is ideal for Arduino, ESP32, and other microcontroller-based projects requiring alarms, notifications, or feedback sounds.
