SBT12ELHMPPC

Overview

The SBT12ELHMPPC is a piezoelectric buzzer from the Mallory Sonalert SBW series, designed for through-hole mounting. It operates on a 9V to 12V DC supply with a current rating of 630 mA. The device features a round shape with a diameter of 44.45 mm and a height of 15 mm. It delivers a sound pressure level between 85 dB and 95 dB within a frequency range of 150 Hz to 4 kHz. Operating temperatures span from -30°C to +65°C, and it utilizes solder termination for PCB integration.

Feature Summary

• IEC-compliant cardiac alarm signaling capability
• Piezoelectric transducer technology for reliable audio output
• Through-hole PCB mounting design

Applications

• Cardiac monitoring systems
• Medical patient monitoring equipment
• Industrial IEC medical alarms

Procurement Notes

Verify the specific suffix HMPPC against official Mallory Sonalert documentation to confirm compliance with required medical standards and RoHS directives. Ensure the ordering part number matches the exact voltage and acoustic specifications needed for the target application before procurement.

Selection Notes

Select this component when a dedicated cardiac alarm tone is required in compliance with IEC standards. Consider the 630 mA current draw and 9-12V operating range during circuit design. Verify that the 44.45 mm diameter fits the available PCB space and that the solder termination method aligns with the assembly process.

Part Context

This unit belongs to the SBW series of audio indicators and speakers manufactured by Mallory Sonalert Products Inc. The series focuses on providing standardized audible alerts for critical applications, particularly within the medical device sector where specific acoustic signatures are mandated for safety and regulatory compliance.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic buzzers may not replicate the specific cardiac alarm waveform or IEC compliance required for this application.
