PS Series Piezoelectronic Buzzers

TDK PS Series Piezoelectronic Buzzers are high-performance buzzers that employ unimorph piezoelectric elements and are designed for easy incorporation into various circuits. The buzzers feature much lower power consumption than electromagnetic units and can serve as both a musical tone oscillator and a buzzer due to their design for external excitation and can be used with automated inserters.
