SBT5PMHFPPC

Overview

The SBT5PMHFPPC is an internally driven piezoelectric buzzer from the Mallory Sonalert SBT series. It features a 44.45mm diameter through-hole package with PC pin termination. The device operates on a DC voltage range of 3.3V to 5V, drawing 15-30mA. It produces a sound pressure level of 85dB at 3.3V with a frequency of 2.075kHz. The unit is cUL recognized to IEC60601-1-8 AMD1 and functions within an operating temperature range of -30°C to 65°C.

Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• cUL recognition to IEC60601-1-8 AMD1 standard for medical safety compliance
• Through-hole mounting with PC pins for robust mechanical attachment

Applications

• Medical diagnostic equipment requiring certified audio alerts
• Patient monitoring systems needing reliable acoustic indicators
• Industrial machinery utilizing IEC60601-compliant signaling devices

Procurement Notes

Verify that the specific order matches the SBT5PMHFPPC part number exactly. Confirm the requirement for cUL recognition to IEC60601-1-8 AMD1 if used in regulated medical environments. Ensure the input voltage supply aligns with the 3.3V to 5V DC specification to maintain the rated 85dB output and current draw characteristics.

Selection Notes

Select this component when a medically compliant, internally driven piezo buzzer is required. The 44.45mm size and through-hole format suit applications where PCB space allows for larger acoustic drivers. Consider the 2.075kHz frequency for optimal human audibility in noisy clinical or industrial settings.

Part Context

This part belongs to the Mallory Sonalert SBT series of medical-grade audio indicators. These devices are engineered specifically for healthcare applications where electrical isolation and safety certifications are mandatory. The series offers various acoustic outputs while maintaining consistent form factors for easy replacement in existing designs.

Replacement Considerations

Direct substitutes must match the 44.45mm diameter, 2.075kHz frequency, and IEC60601-1-8 certification. Verify that any alternative maintains the internally driven piezo architecture and compatible 3.3-5V DC operating range.
