SBT5LMMXPC
Overview
The SBT5LMMXPC is a specialized piezo indicator from Mallory Sonalert designed specifically for medical equipment. It is CUL recognized to the IEC60601-1-8 AMD1 standard for medical alarms, featuring an Oxygen Melody and a silence mode. The device is internally driven and operates on a 3.3V to 5V DC input, eliminating the need for complex external drive circuitry.
Why Choose This Part
This indicator provides a high sound pressure level of 85dB at 10cm using only 15 to 20mA of current. Its pin-selectable operating mode allows engineers to switch between alarm melodies and silence without complex firmware-controlled PWM, ensuring compliance with medical regulatory requirements for auditory alarms.
Applications
Key Specifications
Getting Started
To integrate this buzzer, provide a stable 3.3V to 5V DC supply and use the five-pin through-hole layout to select the desired melody via hardware logic or GPIO. Because it is an internally driven indicator, no external frequency generation is required; simply apply voltage to the appropriate pins to trigger the programmed medical melody.
