Active 5V buzzer 3kHz - 5 pcs

This buzzer generates a tone of approximately 85db (at a distance of 10 cm) when connected directly to a voltage between 4V and 8V. Because this buzzer actively generates a tone, no microcontroller is needed to make the buzzer sound. The buzzer consumes approximately 30 mA and has a tone frequency of approx 3 kHz.
