SBT12DHCFPPC

Overview

The SBT12DHCFPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 9 to 12V and draws a supply current of 630 mA. The device produces a sound pressure level of 100 dB at a frequency of 150 Hz to 4 kHz. It features a round shape with a diameter of 44.45 mm and a height of 15 mm. The unit utilizes PCB mount installation with solder termination. It is designed for cardiac alarm applications and complies with IEC standards.

Feature Summary

• Internal drive circuitry for direct connection without external drivers
• IEC 60601-1 compliant design suitable for medical equipment
• Cardiac-specific acoustic profile optimized for critical alarms

Applications

• Medical cardiac monitors
• Patient monitoring systems
• Hospital alarm panels

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required IEC certifications and acoustic profiles. Confirm that the solder termination method aligns with the target PCB assembly process. Check for RoHS compliance status as defined in the latest product documentation before finalizing procurement specifications.

Selection Notes

Select this component when a high-intensity, low-frequency cardiac alarm tone is required within a compact form factor. Ensure the operating environment supports the specified temperature range and that the PCB layout accommodates the 44.45 mm diameter footprint. Validate that the 12V DC supply matches the system power architecture.

Part Context

This part belongs to the SBT series of industrial-grade audio indicators from Mallory Sonalert. The series focuses on robust performance for medical and industrial environments. The SBT12DHCFPPC variant specifically targets cardiac alarm requirements, distinguishing it from general-purpose or perfusion alarm models within the same family.

Replacement Considerations

Consult the official Mallory Sonalert substitution guide for verified equivalents. Cross-reference electrical parameters such as voltage, current, and SPL to ensure functional compatibility.
