Compact, Reliable Sound Solutions for Your Electronic Projects
PCB buzzers are essential audio alert components designed to provide clear, audible notifications in electronic circuits and devices. These compact sound generators mount directly onto printed circuit boards, making them ideal for space-constrained applications where reliable audio feedback is critical.
Key Features
Versatile Sound Options: Available in both active and passive configurations. Active buzzers include built-in oscillator circuits for plug-and-play operation, while passive buzzers offer frequency control flexibility for custom tones and melodies.
Compact PCB-Mount Design: Low-profile construction with through-hole or surface-mount options fits seamlessly into your board layout. Standard pin spacing ensures easy integration with most PCB designs.
Wide Operating Range: Typically operates on 3V to 12V DC power supply with current consumption as low as 10-30mA, making them suitable for battery-powered and low-power applications.
Clear Audio Output: Produces sound levels ranging from 70dB to 95dB at 10cm distance, ensuring alerts are audible in typical operating environments.
Durable Construction: Robust plastic housing with metal sound chamber provides reliable operation in industrial environments with excellent resistance to vibration and temperature variations.
