SBT5GHPC

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

Overview

The SBT5GHPC is a medical-grade internally driven piezo buzzer designed specifically for high-priority alarm signaling. It operates between 3.3V and 5V DC and produces a repeating 150Hz to 4kHz chime every 2.5 seconds. This through-hole component delivers a sound pressure level of 85dB at 10cm while maintaining a typical current consumption of less than 35mA.

Why Choose This Part

This indicator features an internal driver that simplifies circuit design by requiring only a DC voltage to operate. It is UL and cUL approved for medical applications, ensuring compliance with strict safety standards for audible signaling devices.

Applications

Medical High Priority Alarms
Meets specific medical signaling requirements for critical patient monitoring equipment.
Critical Safety Systems
Utilized in industrial control panels where high-reliability audible alerts are mandatory.
Diagnostic Equipment
Integrated into laboratory instruments to provide clear, repeating status indicators for operators.
