Active Buzzer 1.5V, 2.3KHz

The TMB-12A01 active buzzer is a compact sound signaling component for low-voltage DC circuits. Upon applying the supply voltage, it generates an acoustic tone without the need for an external driving signal. It is designed for integration into electronic devices where simple audio indication of status, alerts, or alarms is required.
