Overview
The SBT12PHCMPPC is a piezoelectric buzzer from the Mallory Sonalert SBW series, designed for medical alarm applications compliant with IEC 60601-1-8 standards. It operates on a 9V to 12VDC supply and features a round, 44.45mm diameter housing with PCB mount termination. The device produces a high-priority perfusion sound tone at approximately 2.075kHz with an acoustic output of 85dB at 9V. Electrical characteristics include a current draw of 15 to 25mA and an internal driving circuit. It functions within a temperature range of -30°C to +65°C.
Feature Summary
- Complies with IEC 60601-1-8 medical alarm standards for high-priority perfusion alerts
- Integrates internal driving circuitry for simplified interface requirements
- Utilizes a 45mm piezoelectric transducer technology for reliable acoustic performance
Applications
- Medical equipment requiring high-priority perfusion alarms
- Hospital patient monitoring systems
- Clinical diagnostic devices
Procurement Notes
Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required medical standards and acoustic specifications. Confirm that the PCB mounting pin layout matches the target design footprint. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the operating voltage range aligns with the system power supply architecture.
Selection Notes
Select this component when a dedicated, internally driven medical-grade alarm is required for perfusion events. The integrated circuitry reduces external component count compared to passive buzzers. Consider the 44.45mm form factor for panel or board space constraints. Verify that the 85dB acoustic level meets the ambient noise requirements of the intended clinical environment.
Part Context
This part belongs to the Mallory Sonalert SBW series, which specializes in audio indicators and alerts. The series includes various configurations for different voltage ratings and sound types. The SBT12PHCMPPC specifically targets the medical sector, distinguishing itself through adherence to international safety and alarm standardization protocols for critical care equipment.
Replacement Considerations
Consult the official Mallory Sonalert substitution guide for verified equivalents. Generic piezo buzzers may lack the required internal driver or medical certification. Ensure any substitute maintains the same mounting dimensions and electrical parameters to avoid redesign.
FAQ
Is the SBT12PHCMPPC internally driven?
Yes, the device includes an internal driving circuit, allowing it to operate directly from a DC voltage source without external oscillators.
What is the primary application sound type for this model?
It is designed for high-priority perfusion alarms as defined by IEC 60601-1-8 standards.
