SBT12VMHMPPC

Overview

The SBT12VMHMPPC is a piezoelectric buzzer from the Mallory Sonalert SBW series, designed for industrial applications. 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 across a frequency range of 150 Hz to 4 kHz. Operating temperatures span from -30°C to +65°C. Installation is achieved via PCB mount using solder terminals.

Feature Summary

• Industrial-grade construction compliant with IEC standards
• Integrated internal driver circuitry for direct activation
• Cardiac alert tone configuration for medical signaling
• Piezoelectric transducer technology for reliable acoustic output

Applications

• Medical equipment cardiac alarms
• Industrial safety warning systems
• IEC-compliant audio alerting devices

Procurement Notes

Verify the specific voltage tolerance and current consumption against your system power budget before integration. Confirm that the PCB footprint matches the solder terminal layout specified in the official datasheet. Ensure the operating environment remains within the stated temperature range of -30°C to +65°C to maintain performance integrity and component longevity.

Selection Notes

Select this component when a dedicated cardiac alert tone is required for medical or industrial safety applications. The integrated driver simplifies circuit design by eliminating external oscillators. Consider the 44.45 mm diameter and 15 mm height for enclosure space constraints. Verify compatibility with 9V to 12V DC power rails and ensure sufficient current capacity for the 630 mA draw.
