S&S SFN-1207PA6.5

This piezoelectric buzzer uses a PZT ceramic element as the sound-generating component, producing sound by vibrating under an applied AC voltage. The product structure comprises a metal plate, piezoelectric ceramic element, resonance cavity, and lead wires, typically housed in SMD or through-hole packages. The operating frequency range is 2 kHz ~ 4.5 kHz, rated voltage is 3 V ~ 24 V, and sound pressure level is 85 dB ~ 105 dB (measured at 10 cm distance). The device features low power consumption, fast response, long service life, and high reliability, making it suitable for audio indication in various electronic equipment. During testing, the buzzer is placed in a free-field acoustic environment and measured using a sound level meter and frequency analyzer.
