The DB-E1898 Piezo Transducer is a compact externally driven piezoelectric sound transducer designed for electronic equipment, embedded systems, alarms, consumer electronics, and industrial control applications. Operating with a 3V drive signal and supporting up to 25Vp-p drive voltage, this transducer delivers a clear 75dB sound output at 10cm, making it ideal for audible indicators, warning devices, and programmable sound generation.
Unlike self-driven buzzers, the DB-E1898 requires an external oscillator or square wave signal from a microcontroller or driver circuit. This allows designers complete control over the output frequency, tone, and pulse patterns, making it an excellent choice for custom electronic applications and embedded systems.
Its compact square black housing is designed for easy PCB integration, while the solid-state piezoelectric construction provides low power consumption, excellent reliability, and a long operational lifespan. The lightweight design makes it suitable for portable and battery-powered equipment.
The DB-E1898 is ideal for OEM products, alarm systems, electronic instruments, medical devices, handheld equipment, educational electronics, and DIY projects requiring reliable, externally controlled audible output.
