5v Active Buzzer

This 5v Active Buzzer provides reliable audible signaling in a compact package for electronic projects and devices. Its active design includes a built-in oscillator, so it requires only a DC voltage input to produce sound and does not need external driving circuitry. Operating voltage: 5 volts, compatible with standard microcontroller outputs. Typical sound frequency: approximately 3 kHz for clear, attention-grabbing tones. Compact size: 12 mm diameter to fit into tight enclosures and small PCBs. Low current consumption: around 30 mA, supporting energy-efficient designs and longer battery life in portable applications. Because the buzzer contains an internal oscillator, it simplifies circuit design compared with passive buzzers that require external pulse generation. The steady tone output and modest power draw make it well suited for alert systems, timers, alarms, confirmations, and user-interface feedback. Its 5v operation aligns with common platforms such as Arduino and Raspberry Pi, facilitating quick integration into prototypes and finished products. The compact footprint allows flexible placement within enclosures while maintaining effective sound output for many short-range signaling needs. Overall, this 5v Active Buzzer is a straightforward, dependable choice when you need consistent audible alerts with minimal external components.
