SBT5GLPC
Overview
The SBT5GLPC is a medical-grade, internally driven piezo buzzer designed to meet specific low-priority alarm requirements. It features a repeating pattern of two beeps every 20 to 30 seconds and operates within a voltage range of 3.3V to 5V. As an internally driven indicator, it simplifies system design by generating its own acoustic frequency between 150Hz and 4kHz without requiring an external PWM source.
Why Choose This Part
This component is UL and cUL approved, ensuring compliance for regulated medical and industrial safety applications. Its integrated circuitry eliminates the need for external drive components, and the through-hole PC pin termination allows for secure, vibration-resistant mounting on a PCB.
Applications
Key Specifications
Getting Started
To use this buzzer, simply apply a DC voltage between 3.3V and 5.5V across the two PC pins; the internal circuitry will automatically generate the 85dB alarm cadence. No external oscillator or software-driven PWM is required, making it easy to trigger directly from a microcontroller GPIO through a simple transistor switch or logic gate.
