The Mini Electromagnetic Alarm Buzzer 3V (Black) is a compact two-pin buzzer that produces a continuous audible tone as soon as power is applied, making it ideal for alerts, timers, and simple feedback circuits. Its small cylindrical housing solders directly onto a PCB or plugs straight into a breadboard for quick prototyping.

Key features:

  • Rated Voltage: Designed to operate at 3V DC for low-voltage microcontroller and battery-powered projects.
  • Continuous Tone: Produces a steady alert sound the moment power is applied, with no driver circuit required.
  • Compact Housing: Small black cylindrical body with two through-hole pins for easy mounting.
  • Low Current Draw: Draws only a few milliamps, safe to switch from most microcontroller pins via a transistor driver.
  • Wide Application: Suitable for alarms, reminders, game feedback, and general notification circuits.

It is a low-cost way to add clear audible feedback to any Arduino, ESP32, or general-purpose electronics project.
