Product Description

RS PRO 0237984P is a professional-grade surface mount piezo buzzer engineered for compact applications requiring reliable and high-output sound signalling. Featuring a continuous tone and an external drive circuit, this buzzer is tailored for clear and consistent alerts in devices such as mobile printers, payment terminals, and digital cameras.

With its 88 dB SPL sound output, the buzzer ensures audible notifications even in noisy environments. It operates across a frequency range of 3.6 kHz to 5 kHz, making it ideal for general audio feedback as well as attention-grabbing alerts. The device is RoHS compliant, meeting rigorous environmental and material standards for safety and sustainability.

Designed for surface mount technology (SMT), the piezo buzzer offers a low-profile height of 7.8 mm and a square footprint of 16.9 mm × 16.9 mm, enabling easy integration onto compact circuit boards. Its external drive requirement allows for flexible control schemes, compatible with a variety of electronic platforms. The buzzer has a low supply current of 10 mA, minimizing energy demand and supporting portable or battery-operated devices.

With an operating temperature range from −30°C to +70°C, the buzzer is robust for both indoor and outdoor environments. High capacitance of 19,000 pF supports stable performance, while the maximum supply voltage of 20V AC ensures versatile compatibility.

Typical industrial, laboratory, and commercial applications include point-of-sale equipment, portable electronics, security panels, and automation systems where clear acoustic cues are essential. The compact, lightweight, and reliable build makes RS PRO 0237984P a preferred choice for volume manufacturing and professional assemblies.
