SBT12XMCMPPC

Overview

The SBT12XMCMPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It features an internal driver circuit and operates on DC input within a voltage range of 9V to 12V. The device draws a supply current of 630mA and produces a sound pressure level of 100dB. It is designed for through-hole mounting with a diameter of 44.45mm.

Feature Summary

• Piezoelectric technology with integrated internal driver circuit
• High acoustic output capability at specified operating voltages
• Robust construction suitable for industrial audio alerting applications

Applications

• Industrial cardiac monitoring alarms
• Medical perfusion pump alerts
• General purpose high-decibel warning systems

Procurement Notes

Verify the specific acoustic waveform designation (e.g., Cardiac or Perfusion) required for your application, as Mallory Sonalert products often vary by tone pattern despite identical electrical ratings. Confirm that the 630mA current draw is supported by your power supply infrastructure before integration. Ensure the through-hole footprint matches your PCB layout constraints.

Selection Notes

Select this component when a high-intensity audible alert is necessary in environments requiring reliable piezoelectric performance. The 100dB rating makes it suitable for noisy industrial settings. Consider the 630mA current consumption during power budget calculations. Verify compatibility with 9-12V DC control signals from microcontrollers or relay drivers.

Part Context

This part belongs to the SBT series of industrial-grade audio indicators. Mallory Sonalert designs these units for harsh environments, often carrying certifications such as UL and cUL. The SBT series typically includes variants differentiated by sound waveforms tailored for specific medical or industrial safety standards.

Replacement Considerations

Direct replacements must match the 44.45mm diameter, 630mA current draw, and 100dB SPL. Verify that substitute parts support the same specific acoustic waveform (Cardiac/Perfusion) if used in regulated medical equipment. Check terminal type compatibility for through-hole mounting.
