SBT5VLHFPPC

Overview

The SBT5VLHFPPC is an internally driven piezoelectric buzzer from the Mallory Sonalert SBT5 series. It operates on a DC voltage range of 3.3 to 5V and draws between 15 and 30mA. The device produces an acoustic output of 85dB at 3.3V measured at 10cm, with a resonant frequency of 2.075kHz. It utilizes through-hole PC pin termination for board mounting.

Feature Summary

• Internally driven piezoelectric technology
• Through-hole PC pin termination
• IEC 3.3-5VDC operation

Applications

• Medical equipment audio indicators
• Industrial control panel alerts
• Consumer electronics status signals

Procurement Notes

Verify the specific suffix HFPPC against official Mallory Sonalert documentation to confirm exact acoustic characteristics and termination style. Ensure compatibility with IEC 3.3-5VDC supply rails. Confirm RoHS compliance status via current manufacturer datasheets before integration into regulated medical or industrial designs.

Selection Notes

Select this component for applications requiring low voltage operation and high acoustic output relative to power consumption. The internal driver simplifies circuit design by eliminating external oscillators. Verify that the 2.075kHz frequency meets auditory alert requirements for the target environment.

Part Context

This part belongs to the SBT5 series of audio indicators manufactured by Mallory Sonalert Products Inc. The series is designed for board-level integration in various electronic systems.
