BPC2310 23mm 12V Active Piezo Buzzer | Continuous Tone 90dB Internal Drive Piezoelectric Buzzer

The BPC2310 active piezoelectric buzzer is a ready-to-use acoustic alarm component with built-in driving circuit. Different from passive piezo buzzers, this model works directly with DC power without extra drive circuit. With resonant frequency at 3500±500Hz and stable continuous tone output, this pin-type piezo buzzer provides loud and clear warning sound. The PBT plastic shell delivers outstanding heat resistance, supporting wide operating temperature from -20℃ to +70℃, which makes it reliable for indoor and semi-outdoor electronic warning products. It is a standard 23*10mm buzzer, through-hole pin mounting for easy soldering on PCB boards. Strict quality control ensures consistent sound volume and long service life for mass production projects.
