SBT12MMXPC
Overview
The SBT12MMXPC is a specialized medical-grade piezo buzzer designed to meet strict IEC60601-1-8 AMD1 oxygen melody requirements. This internally driven indicator operates on a 9V to 12V DC input and produces a high-priority 10-beep alarm sequence repeating every 2.5 seconds.
Why Choose This Part
This buzzer simplifies compliance by integrating the specific IEC60601-1-8 melody directly into the hardware, removing the need for complex software-driven PWM timing. Its piezo technology ensures low current consumption (15 to 20mA) while delivering a clear 85dB output at 10cm.
Applications
Key Specifications
Getting Started
To integrate the SBT12MMXPC, provide a stable 9V to 12V DC source to the appropriate pins; the internal circuitry handles all oscillation and timing for the oxygen melody. The through-hole PC pins allow for direct mounting to a PCB, but ensure the top-port location is not obstructed to maintain specified decibel levels.
