SBT12PLHMPPC

Overview

The SBT12PLHMPPC is a board-mount piezoelectric buzzer from Mallory Sonalert. It operates on a 9-12VDC supply and produces an 85dB sound level at 9V. The device features a resonant frequency of 2.075kHz with a current draw between 15-25mA. It utilizes through-hole PC pins for mounting and has a diameter of 44.45mm.

Feature Summary

• Internally driven piezoelectric design
• Through-hole PCB mounting via PC pins
• High acoustic output capability

Applications

• Perfusion pump audio alerts
• Medical equipment status indicators
• Industrial control panel alarms

Procurement Notes

Verify the specific suffix 'MPPC' against official Mallory Sonalert documentation to confirm exact acoustic and electrical tolerances. Ensure the ordering part number matches the required voltage and decibel specifications for the target application environment.

Selection Notes

Select this component when a high-volume, internally driven piezo buzzer is required for medical or industrial panels. The 44.45mm diameter fits standard mounting holes. Confirm that the 9-12VDC operating range aligns with the system power supply before integration.

Part Context

This unit belongs to the SBT series of board-mount buzzers. It is designed for direct integration into printed circuit boards using through-hole technology. The product line emphasizes reliable audio signaling for critical infrastructure and healthcare devices.

Replacement Considerations

Check for SBW series variants if speaker-style output is needed instead of piezo buzzing. Verify physical dimensions and pinout compatibility before substituting with other Mallory Sonalert models.
