Piezo Buzzer (14mm)

How does it work?

Piezo Buzzer (EPT-14A4005P) is an audio signalling device powered by DC voltage to produce a tone, alarm, or sound from Sanco Electronic. As its name suggests, a Piezo Buzzer’s core comprises the piezoelectric ceramic element, as well as a metal plate held together by adhesive. When an AC current is passed through, the piezo-ceramic element contracts and expands, which causes a vibration that produces sound waves.

This circular TH piezo buzzer has a diameter of 13.8×6.8mm, a resonant frequency of 4000Hz (the frequency at which the buzzer vibrates), draws a maximum current of 2mA, and a wide operating voltage range – from 1 to 25V (typical 5V). Thanks to its reliability and flexibility, it makes an excellent choice for various audible applications ranging from alarms to automobile alerts, consumer electronics, and more.
