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.
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.
Buzzers Transducer, Externally Driven Piezo 3V 1mA 4kHz 70dB @ 3V, 10cm Through Hole PC Pins
Buzzers Indicator, Internally Driven Piezo 12V 120mA 2.5kHz 105dB @ 12V, 30cm Panel Mount, Flange Wire Leads
Buzzers Transducer, Externally Driven Piezo 15V 8mA 4.8kHz 85dB @ 4.8V, 10cm Panel Mount, Flange Wire Leads
