SBT5VMHMPPC

Overview

The SBT5VMHMPPC is a piezoelectric buzzer from the Mallory Sonalert SBT5 series, designed for medical applications. It operates on a DC input with a rated voltage of 5V and a range of 3.3-5VDC. The device features internal drive circuitry and variable duration control. Key electrical parameters include a frequency of 2.075kHz and a sound pressure level of 90dB. It utilizes through-hole mounting with PC pins and measures 44.45mm in diameter.

Feature Summary

• Complies with IEC 60601-1-8 standards for medical audio signaling
• Features internal drive circuitry for direct interface compatibility
• Provides variable duration alarm signaling capabilities
• Constructed with piezoelectric technology for reliable acoustic output

Applications

• Medical equipment audio alarms
• Hospital patient monitoring systems
• Clinical diagnostic devices
• Healthcare safety indicators

Procurement Notes

Verify that the specific suffix PP indicates the required pin configuration and housing material for your assembly. Confirm compliance with IEC 60601-1-8 standards if used in life-support or critical care environments. Ensure the 5V DC supply matches the component's rated voltage to maintain specified acoustic performance and longevity.

Selection Notes

Select this model when medical regulatory compliance is mandatory. The 90dB output ensures audibility in noisy clinical settings. The through-hole package suits PCB designs requiring robust mechanical anchoring. Verify that the 2.075kHz frequency aligns with user perception requirements for the specific medical application context.

Part Context

This component belongs to the SBT5 series of panel-mount buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by its focus on medical-grade reliability and standardized alarm tones. The SBT5VMHMPPC specifically denotes the VM (variable melody) tone variant with medical certification and through-hole termination.

Replacement Considerations

Direct replacements must match the 5V DC rating, 44.45mm diameter, and IEC 60601-1-8 certification. Verify that substitute parts offer equivalent 90dB SPL at the operating distance and compatible through-hole pin spacing to ensure mechanical and electrical interchangeability without redesign.
