SBT12GMPC
Overview
The SBT12GMPC is an internally driven piezo audio indicator designed for medium-priority alarm signaling. Operating from a DC input of 9V to 12V, it produces a repeating pattern of three beeps every 7.5 seconds with a sound pressure level of 85dB at 10cm. This sounder simplifies system design by integrating the driver circuitry directly into a compact through-hole package.
Why Choose This Part
The internal driver eliminates the need for an external oscillator or complex PWM timing, reducing MCU overhead and component count. Its piezo technology ensures low power consumption with a typical current draw of less than 25mA while maintaining a high 85dB output.
Applications
Key Specifications
Getting Started
To use this indicator, apply a steady 9V to 12V DC voltage to the PC pins; the internal circuitry automatically manages the 7.5-second repeating beep interval. Ensure the top-facing port is unobstructed to maintain the rated 85dB sound pressure level during installation.
