Description

The Piezoelectric Buzzer is a small and efficient component to add to your system or project if you want to produce any sound feedback or sound an alarm. Its two-pin compact structure allows it to be easily used with a breadboard, perf-board, or even PCBs. This piezoelectric buzzer has 23mm diameter and 30mm spaced mount holes. It produces a 3.3kHz tone at an 85dB sound level when activated drawing a current less than 15mA. Supplied with a 100mm lead, it is designed for a 3 – 20V power supply but it is advisable to use a stable supply in this range. It is very popular among hobbyists and portable electronics due to its small size.
