Small Piezoelectric Buzzer, 5V Passive

The Small Piezoelectric Buzzer is a compact 5V passive buzzer built for projects that need a clear, dependable audio alert without drawing much current from the circuit. Unlike an active buzzer, this passive unit needs a driving signal from a microcontroller or timer IC to generate sound, giving you control over pitch and pattern rather than a fixed tone. Its small footprint and light weight make it easy to fit onto a breadboard, perfboard, or a finished PCB layout.

Internally the buzzer uses a coil element that vibrates a diaphragm to produce sound, resonating most strongly around its rated frequency. With a body size of just 12 x 8mm and a 6mm pin pitch, it drops neatly into standard header spacing used across most hobbyist boards, and its plastic housing keeps it light enough for wearable or portable builds.

• Input Voltage (Max.) – 5V
• Resistance – 42 Ω
• Resonance Frequency – 2048 Hz
• Body Size – 12 x 8mm
• Pin Pitch – 6mm
• External Material – Plastic
• Buzzer Type – Passive (requires driving signal)
• Mounting – Through-hole, breadboard/PCB friendly

Well suited to alarms, notification circuits, timers, and general-purpose feedback tones in Arduino or microcontroller-based projects, this Small Piezoelectric Buzzer is a reliable choice wherever a compact audio indicator is needed.
