21mm Piezoelectric Ceramic Buzzer beep

A 12mm piezoelectric ceramic buzzer is a compact sound-producing component commonly used in electronic devices. This type of buzzer operates on the principle of piezoelectricity, where mechanical stress is apply to ceramic material to produce an electrical signal, which is then convert into sound. With a small 12mm diameter, this buzzer is ideal for applications where space is in limit point but audible alerts are necessary, such as in consumer electronics, alarm systems, timers, and household appliances.

The buzzer generates a clear, high-pitch tone when voltage is apply, making it highly efficient for signaling purposes. It typically requires low power consumption, which is crucial for battery-operated devices. The piezoelectric buzzer is durable, with a long operational life and reliable performance, even under varying environmental conditions.

Its small size and lightweight design allow for easy integration into printed circuit boards (PCBs) and other compact electronic assemblies. The 12mm piezoelectric ceramic buzzer is available in both active and passive variants, with the active type generating sound when powered, while the passive type requires an external signal to produce sound.

Overall, this versatile component offers an efficient and reliable solution for audio indication in numerous electronic applications.
