🔍 Product Overview

The 3 V Active Electromagnetic Buzzer is a compact audio signaling component designed to operate from a ~3 V DC supply. It includes its own internal driver circuit, so once powered it emits a continuous tone without needing an external oscillator—making it ideal for alerts, alarms, notifications or user-feedback in electronics systems.

🚀 Why It’s Ideal for Your Projects

• Low voltage compatibility: Designed to run at 3 V, making it perfect for battery-powered devices, low-voltage sensor modules or microcontroller interfaces.

• Plug-and-play behavior: Because it’s “active,” you simply apply the supply voltage and it generates sound—no external PWM or tone-generation circuits needed.

• Compact integration: With a small footprint and two connection leads, it meshes well into PCBs, embedded systems or compact enclosures.

📝 Key Features

• Rated voltage: 3 V DC (typical operating range around ~2.5 V to ~4 V)

• Sound pressure level: Typically 80 dB(A) or more at ~10 cm distance

• Resonant frequency: Around 2.048 kHz (varies by model)

• Impedance/coil resistance: Approximately 30 Ω (varies)

• Package size: Compact body, example ~12 mm × 9.5 mm with through-hole PCB lead pins (pin pitch ~6 mm)

• Operation style: Continuously emits tone upon applying voltage (unless externally modulated)

🎯 Typical Applications

• Alarm and notification systems: Ideal for security panels, timers, doorbell circuits, or low-voltage alert indicators.

• User feedback in embedded electronics: Give audible confirmation for button presses, sensor thresholds, or event notifications in hobbyist or educational projects.

• Battery-powered or portable devices: Because of its low voltage and low current draw, it suits handheld or stand-alone electronics.

• Educational builds & prototyping: Great for teaching about audible signaling, driver circuitry and simple integration into microcontroller systems.
