SBT5VMHCTPC

Overview

The SBT5VMHCTPC is a piezoelectric buzzer from the Mallory Sonalert SBT series, designed for through-hole panel mounting. It operates on a DC input voltage range of 3.3V to 5VDC. The device features an internal driver circuit and produces a sound pressure level of 90dB at a distance of 61cm. It functions as a perfusion alarm indicator with a single-tone output mode. The unit is constructed to withstand operating temperatures between -30°C and +65°C.

Feature Summary

• Integrated internal driver circuit for direct connection
• High-intensity 90dB acoustic output for clear alerting
• Through-hole mounting configuration for secure installation
• Compliant with IEC standards for medical perfusion alarms

Applications

• Medical perfusion pump alarm systems
• Hospital infusion monitoring devices
• Industrial process control audio indicators
• Healthcare equipment status signaling

Procurement Notes

Verify the specific suffix HCTPC against official Mallory documentation to confirm the exact acoustic profile and mounting style. Ensure the input voltage matches the 3.3-5VDC requirement. Confirm RoHS compliance status via the manufacturer's current certification documents before finalizing procurement specifications.

Selection Notes

Select this component when a high-decibel, internally driven piezo buzzer is required for medical or industrial applications. The 90dB output ensures audibility in noisy environments. Verify that the through-hole package fits the PCB layout and that the 3.3-5VDC supply rail is stable for reliable operation within the specified temperature range.

Part Context

This part belongs to the SBT series of audio indicators manufactured by Mallory Sonalert Products Inc. The series is recognized for providing robust warning solutions for critical infrastructure. The SBT5VMHCTPC specifically targets the medical sector, offering a standardized form factor for integration into diagnostic and therapeutic equipment requiring precise auditory feedback.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic piezo buzzers may not match the 90dB SPL or internal driver characteristics. Ensure any substitute meets the same IEC medical safety standards and physical dimensions.
