SBT12XHCFPPC

Overview

The SBT12XHCFPPC is a piezoelectric buzzer from the SBW series, designed for PCB mounting with solder termination. It operates on a voltage range of 9 to 12 VDC and draws approximately 630 mA. The device produces a sound pressure level between 85 dB and 95 dB within a frequency range 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 functions reliably within an operating temperature range of -30°C to +65°C.

Feature Summary

• Internally driven piezoelectric technology for direct signal input
• Cardiac alarm tone configuration for medical applications
• PCB mount design with solder pin termination
• IEC 60601-1-8 compliance for oxygen melody priority signaling

Applications

• Medical equipment requiring high-priority cardiac alarms
• Oxygen therapy devices needing specific IEC-compliant alerts
• Industrial control panels requiring audible status indicators
• Automotive systems utilizing standard DC power supplies

Procurement Notes

Verify the complete part number including suffixes such as PPC to ensure correct packaging and terminal type. Confirm that the application environment stays within the specified -30°C to +65°C operating range. Check for required certifications like cUL or RoHS depending on regional regulations. Ensure the driving circuit can supply the necessary current without exceeding voltage limits.

Selection Notes

Select this component when a compact, internally driven buzzer is needed for PCB integration. The SBW series offers a balance of size and acoustic output suitable for panel-mounted or board-level designs. Consider the specific tone requirements, such as the cardiac melody, against other available frequencies in the Mallory Sonalert portfolio. Verify mechanical fitment against the 44.45 mm diameter constraint.

Part Context

This part belongs to the SBW series of speakers and transducers manufactured by Mallory Sonalert Products Inc. The series focuses on robust audio indicators suitable for demanding environments. The SBT12XHCFPPC variant specifically addresses medical and industrial sectors requiring compliant alarm tones. It represents a standardized solution for audible alerting in electronic assemblies.

Replacement Considerations

Direct substitutes may include other Mallory Sonalert SBW series parts with matching voltage and form factor. Cross-reference internal drive capabilities and acoustic output levels before substitution. Ensure any replacement meets the same IEC 60601-1-8 standards if used in medical contexts.
