SBT5GMPC

Mallory Sonalert Products Inc.
Buzzers Indicator, Internally Driven Piezo 35mA 150Hz ~ 4kHz 85dB @ 3.3V, 10cm Through Hole PC Pins
Active

Overview

The SBT5GMPC is a specialized medical-grade piezo buzzer designed to meet IEC 60601-1-8 requirements for medium-priority alarms. This internally driven indicator produces a 150Hz to 4kHz chime that repeats every 7.5 seconds when power is applied. Operating between 3.3V and 5V, it simplifies system integration by eliminating the need for complex external drive circuitry or PWM timing control.

Why Choose This Part

This component features a pre-programmed internal driver that ensures precise timing for the 7.5-second repeat interval without software overhead. It offers a high sound pressure level of 85dB at 3.3V while maintaining a low typical current consumption of less than 35mA. Its broad frequency range and medical-grade ratings make it a drop-in solution for regulatory compliance in healthcare environments.

Applications

Getting Started

To integrate the SBT5GMPC, provide a stable DC supply between 3.3V and 5.5V to the through-hole pins; the internal circuitry will automatically handle the chime oscillation and timing. Ensure the top-facing port is not obstructed by the enclosure to maintain the rated 85dB output. For software-controlled silencing, use a simple NPN transistor or MOSFET low-side switch to gate the buzzer power.
