Here's a detailed description of such a buzzer:

Type: Active buzzer - This means that the buzzer generates sound when powered, usually by producing an oscillating signal internally.

Supply Voltage: 5V DC - The buzzer operates within a voltage range of 5V, making it compatible with standard 5V power sources commonly found in electronic circuits.

Mounting: Designed for PCB mounting - The buzzer is intended to be soldered directly onto a printed circuit board, making it suitable for integration into various electronic devices and projects.

Size: 10mm - This dimension typically refers to the diameter of the buzzer. A 10mm buzzer is relatively compact and can be easily accommodated in small electronic devices or circuits where space is limited.

Sound Output: The buzzer likely produces an audible sound when activated, suitable for providing alerts, notifications, or feedback in electronic devices.

Operating Principle: It may employ various mechanisms to generate sound, such as electromagnetic, piezoelectric, or magnetic-transducer technology. The specific operating principle can affect factors such as power consumption, frequency range, and sound output level.
