A compact active sound transducer (buzzer) with a 12 mm diameter is designed for quick implementation of audible signaling in a variety of electronic devices and projects. The key feature of an active buzzer is its built-in oscillator: to produce sound, it is enough to apply a constant supply voltage of 5 V to the terminals, unlike passive counterparts that require an external frequency signal. The product features through-hole terminals for soldering into printed circuit board holes (THT) and a protective adhesive label on the housing. Features: Product type: active buzzer / sound component (Active Buzzer Transducer) Specifications: operating voltage 5 V, housing diameter 12 mm, built-in sound oscillator, lead terminals for mounting on a board Purpose: generating audio signals, alerts, and alarm and informational buzzers in electronic devices
