SBT12DMHSPPC

Overview

The SBT12DMHSPPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at a frequency of 2.075kHz and produces a sound pressure level of 85dB when tested at 9V. The device draws between 15 and 25mA during operation. It features a diameter of 44.45mm and is designed for through-hole mounting using PC pins. The unit supports a rated voltage of 2.8Vp-p square wave with a power rating of 1W, reaching a maximum of 1.5W. It functions within a temperature range of -30°C to +65°C.

Feature Summary

• Internally driven piezoelectric design for simplified integration
• Medical specification compliance with IEC60601-1-8 AMD1
• Through-hole PC pin mounting configuration

Applications

• Medical equipment alarms
• Industrial warning systems
• Audible indicator circuits

Procurement Notes

Verify the specific suffix PPC against official Mallory documentation to confirm pin configuration and material specifications. Ensure the operating environment remains within the -30°C to +65°C range. Confirm that the 2.8Vp-p square wave input matches the driving circuit capabilities. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when medical safety standards such as IEC60601-1-8 are required. The internal drive capability reduces external component count compared to externally driven transducers. Verify that the 85dB output at 9V meets the acoustic requirements of the target application. Ensure the 44.45mm form factor fits the available enclosure space.

Part Context

This part belongs to the Mallory Sonalert SBT series of audible alarms and buzzers. The series is known for high-performance warning devices under the Sonalert brand. Mallory manufactures a wide range of audible and visual warning products including transducers and speakers. This specific model focuses on medical-grade reliability and standard through-hole integration.

Replacement Considerations

Consult official Mallory cross-reference lists for verified substitutes. Generic piezo buzzers may not meet the IEC60601-1-8 medical certification. Verify that any replacement maintains the 2.075kHz frequency and 44.45mm diameter constraints.
