Product Detail

Key Features & Benefits


Ultra-Compact SMD Design: Measuring just 4.0x4.0x2.0mm, this is one of the smallest buzzers on the market. Its miniature footprint saves critical PCB space, ideal for modern, high-density electronics.


Surface-Mount Technology (SMT): Fully compatible with automated pick-and-place and reflow soldering processes. This significantly reduces assembly time and cost compared to through-hole buzzers, enabling high-volume manufacturing.


High-Sound Output (75dB): Generates a clear, audible 4KHz tone at 75dB (measured at 10cm distance). Ensures reliable user alerts even in moderately noisy environments.


Low Power Consumption (Magnetic Type): SMD magnetic buzzers are more efficient than piezo types at low frequencies and low voltages, making them perfect for battery-powered devices.


Lead-Free and RoHS Compliant: SMD buzzer 3V manufactured with environmentally friendly materials, meeting global environmental standards and regulatory requirements.


Reliable & Consistent Performance: SMD buzzer 3V built with robust materials to ensure stable performance and long-term reliability under various operating conditions.


Applications

This miniature buzzer is perfectly suited for a wide range of electronic devices where size and reliability are paramount.

Wearable Devices: Smartwatches, Fitness Trackers, Health Monitors

Portable Electronics: Bluetooth Headsets, Action Cameras, Portable Media Players

IoT & Smart Home: Sensors, Remote Controls, Smart Locks, Security Tags

Consumer Electronics: Mobile Accessories, Gaming Peripherals, Toys

Medical Devices: Portable Monitors, Drug Delivery Systems (for non-critical alerts)
