Overview
The SBT5XHCFPPC is a piezoelectric buzzer from the Mallory Sonalert industrial-grade audio indicator series. It operates on an IEC standard voltage range of 3.3 to 5VDC and delivers a sound pressure level of 90dB. Designed for panel or board mounting, this component features internal drive circuitry and utilizes surface-mount technology (SMT) termination. The unit is RoHS compliant and engineered for high-reliability applications requiring distinct audible alerts within compact electronic assemblies.
Feature Summary
- Industrial-grade construction designed for robust performance in demanding environments
- Integrated internal drive circuitry simplifies interface requirements
- Surface-mount technology (SMT) facilitates automated assembly processes
- Compliant with RoHS environmental standards
Applications
- Medical device cardiac alarms
- Ventilator failure indicators
- Oxygen level monitoring alerts
- General industrial equipment signaling
Procurement Notes
Verify the specific suffix configuration against the official Mallory Sonalert datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the surface-mount footprint matches the target PCB design. Check for any recent updates to the product lifecycle status or compliance certifications before finalizing procurement orders.
Selection Notes
Select this component when a high-intensity 90dB alert is required within a low-voltage 3.3V to 5VDC system. The SMT package is suitable for designs prioritizing space efficiency and automated manufacturing. Ensure the application environment falls within the specified operating temperature range and does not require through-hole mounting alternatives.
Part Context
This part belongs to the Mallory Sonalert SBT5 series, which specializes in medical and industrial audio indicators. The series focuses on providing reliable, high-decibel alerts using piezoelectric transducers. These components are widely utilized in healthcare and industrial sectors where clear auditory feedback is critical for safety and operational monitoring.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference documentation for verified substitutes. Direct replacements must match the 90dB SPL, 3.3-5VDC input, and SMT form factor. Generic equivalents may lack the specific medical-grade reliability or acoustic profile required for this application.
