Piezoelectric buzzers are a great choice when you’re looking for devices that offer lower power consumption, lack of magnetic field, and no added EMI/EMC concerns. They are often considered alarms or warning tones, and are typically found in timers, computer devices, pest deterrents, telephones, toys, and games. We carry washable, non-washable, and reflow buzzer types in several sizes, frequencies, and sound outputs.

PB Series

PB Series

Here is our selection of piezoelectric buzzers with an internal drive circuit. The frequencies on these buzzers are fixed, but you can operate them with voltage alone.

PT Series

PT Series

These buzzers require an external drive circuit to operate. These buzzers are generally cheaper and more versatile, but there’s a lot more assembly required.
