TMB12A05 12mm 5V Active Magnetic Buzzer (Through Hole)

The TMB12A05 is an active-type magnetic buzzer with a built-in driving circuit, designed to operate directly with a 5V supply voltage. Since it includes an internal oscillator, it can generate sound simply by applying the correct DC voltage, without the need for an external driver or signal source.

With its compact 12mm diameter and through-hole (THT) mounting type, it is widely used in Arduino projects, microcontroller-based systems, alarm circuits, and warning or notification applications. Its electromagnetic structure provides a clear and strong audible output.
