SBT5CMPC

Overview

The SBT5CMPC is a medical-grade piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within an IEC standard voltage range of 3.3 to 5 VDC and delivers a sound pressure level of 90 dBA. The device features a cardiac alarm tone and is designed for board mounting with solder pin termination. It complies with RoHS standards and functions reliably across a temperature range of -30°C to +65°C. The physical dimensions include a diameter of 44.45 mm, making it suitable for compact medical equipment installations requiring high-visibility audio alerts.

Feature Summary

• Complies with IEC standards for medical audio indicators
• Features a specific cardiac alarm tone pattern
• Operates on low voltage DC power supply
• RoHS compliant construction for environmental safety

Applications

• Cardiac monitoring systems
• Medical patient monitors
• Hospital alarm panels
• Clinical diagnostic equipment

Procurement Notes

Verify the exact datasheet version before integration, as specifications may vary between manufacturing batches. Confirm that the 3.3-5VDC operating range matches your system's power rails. Ensure the board mount footprint aligns with your PCB design constraints. Check for any regional compliance certifications required for your target market. Validate the temperature rating against your operational environment limits.

Selection Notes

Select this component when a dedicated cardiac alarm tone is required for medical devices. It is appropriate for applications needing a 90 dBA output in a compact form factor. Consider the 44.45 mm diameter for panel or board space availability. The low voltage operation suits battery-powered or low-power medical systems. Verify compatibility with your enclosure acoustics for optimal sound projection.

Part Context

This part belongs to the SBT series of industrial and medical audio indicators from Mallory Sonalert. The series includes various tones such as drug-fluid and failure alarms. These buzzers are designed for reliability in critical healthcare environments. The SBT5CMPC specifically targets cardiac alerting needs within this broader product line.

Replacement Considerations

Check for direct substitutes within the SBT5 series with different tone codes if cardiac alerts are no longer needed. Verify mechanical compatibility with existing mounting holes due to the 44.45 mm diameter. Ensure electrical parameters remain within the 3.3-5VDC range for seamless integration.
