Features clearly specified electrical and acoustic parameters for circuit design.
Through-hole design is suitable for soldering onto a PCB.
Operating voltage range of 4 to 7 V DC matches common low-voltage electronic applications.
Installation and Operation Instructions
Observe the marked polarity of the component during wiring.
Power only with DC voltage in the range of 4 to 7 V DC.
Verify the pin layout on the PCB before soldering.
When driving from a microcontroller, ensure the output pin or switching element can handle the buzzer’s current draw.
Safety Warnings
Do not exceed the specified operating voltage and maximum current.
Incorrect polarity, short circuits, or overvoltage may damage the component or the connected circuit.
Perform assembly and soldering with the power disconnected.
The component is designed for low-voltage electronic circuits, not for direct connection to mains voltage.
