SBT5PMHMPPC

Overview

The SBT5PMHMPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at 5VDC with a current draw of 15 to 30mA. The device produces an Artificial Perfusion Melody at a frequency of 2.075kHz and a sound pressure level of 85dB @ 3.3V. It features a 45mm diameter, through-hole mounting with 5PC pins, and includes internal circuitry.

Feature Summary

• Generates specific Artificial Perfusion Melody for medical or alert applications
• Internally driven piezoelectric transducer with integrated circuitry
• Through-hole mounting configuration with five pin connections

Applications

• Medical equipment audio alerts
• Hospital monitoring systems
• Industrial alarm panels

Procurement Notes

Verify the exact suffix HMPPC against official Mallory Sonalert documentation to confirm the melody type and pin configuration. Ensure the 5VDC operating voltage matches the target circuit design. Check RoHS compliance status via the manufacturer datasheet before integration into regulated assemblies.

Selection Notes

Select this component when a specific perfusion melody is required rather than a standard tone. The 45mm size and through-hole pins dictate board layout constraints. Confirm that the 85dB output level meets the acoustic requirements of the intended enclosure environment.

Part Context

This part belongs to the SBT5 series of piezoelectric buzzers from Mallory Sonalert. The series offers various melodies and drive voltages. The SBT5PMHMPPC specifically denotes the medium priority perfusion melody variant with high power output capabilities in a standard through-hole package.

Replacement Considerations

Cross-reference with other SBT5 series parts if different melodies are acceptable. Verify pinout compatibility with existing PCB footprints before substituting.
