Piezoelectric Passive SMD Buzzer 3V 4KHz 12x12x3mm

  1. Product Introduction The MLT-1230 is a high-performance SMD Piezo Buzzer, belonging to the classic categories of Passive Buzzer andPiezoelectric Buzzer. It is specially developed for engineering scenarios where designers need to build independent external drive circuits. Different from Piezoelectric Buzzer For Driver Circuit Built-in models with integrated drive modules, this passive component operates purely with external AC voltage drive, making it an optimal sound component for automated SMD assembly and space-saving PCB electronic devices. In the industrial buzzer product ecosystem, thispiezo buzzer features differentiated advantages compared with Electromagnetic Buzzer and Mechanical Buzzer. It abandons the structural defects of electromagnetic and mechanical buzzers and adopts a piezoelectric ceramic deformation vibration sound generation principle. Equipped with a high-quality diaphragm structure consistent withMylar Speaker, it delivers clear, stable and pure warning sou…
