SBT12MMVPC
Overview
The SBT12MMVPC is a specialized medical-grade piezo buzzer designed for high-reliability alert systems. Operating between 9V and 12V DC, this internally driven indicator produces a 2.075kHz tone at 85dB, specifically tuned for medical equipment signaling standards. It features a pin-selectable operating mode allowing engineers to control the audible duration and alert patterns.
Why Choose This Part
The component is specifically rated for medical applications and includes a multi-pin configuration for selecting different operating modes without external circuitry. Its piezo technology ensures low current consumption, typically between 15mA and 20mA, while maintaining a consistent 85dB output level.
Applications
Key Specifications
Getting Started
To integrate this buzzer, connect the common pin and select the desired operation mode by grounding the specific control pin as defined in the Mallory datasheet. Because it is internally driven, it only requires a stable DC voltage between 9V and 12V to operate, eliminating the need for an external oscillator circuit.
