SBT12GHPC

Overview

The SBT12GHPC is a medical-grade internally driven piezo buzzer designed specifically for high-priority alarm signaling. It features a built-in drive circuit that produces a repeating pattern of 10 beeps every 2.5 seconds when powered by a 9V to 12V DC source. This component is cUL recognized to IEC60601-1-8 AMD2:2020 standards, ensuring compliance for life-critical medical equipment notifications.

Why Choose This Part

This piezo indicator simplifies design by integrating the alarm timing and frequency generation into a single through-hole package, removing the need for external software-controlled oscillators. It provides a consistent 85dB to 95dB output and consumes less than 25mA, making it efficient for battery-backed medical devices.

Applications

Getting Started

Integrate the device by providing a stable 9V to 12V DC supply to the PC pins; the internal circuitry will automatically generate the required medical alarm pattern. Ensure the top-port is not obstructed during enclosure design to maintain the rated 85dB sound pressure level. For volume control, use a series resistor or PWM the input voltage, though a steady DC supply is recommended for timing accuracy.
